Master Alteration Specialist (MAS) Certification Exam — Questions and Answers

Question 1: Which type of needle is best suited for sewing knit or stretch fabrics to avoid skipped stitches and holes?

Sharp/microtex needle
Leather wedge needle
Ballpoint or stretch needle (Correct answer)
Topstitch needle

Correct answer: Ballpoint or stretch needle

A ballpoint needle slips between knit loops rather than piercing and cutting the yarns, preventing damage and skipped stitches.

Question 2: What is the best approach to teach pressing during construction?

Press only at the very end
Press each seam as it is sewn (Correct answer)
Use maximum heat on all fabrics
Never press to avoid scorching

Correct answer: Press each seam as it is sewn

Pressing seams as you sew produces a crisp, professional result.

Question 3: What is an industry-standard deposit percentage commonly charged before beginning a custom garment?

10% of the total quoted price
100% of the total quoted price upfront
No deposit; payment is due only upon delivery
50% of the total quoted price (Correct answer)

Correct answer: 50% of the total quoted price

Charging 50% upfront is a widely accepted practice in custom tailoring to cover fabric costs and protect against cancellations.

Question 4: Why does a tailor cut an underlining and the fashion fabric, then baste them together to be treated as one?

To allow the garment to be reversible
To double the seam allowance
To make hemming unnecessary
To add body and prevent show-through while supporting the fashion fabric (Correct answer)

Correct answer: To add body and prevent show-through while supporting the fashion fabric

Underlining backs the fashion fabric to give it more body, reduce transparency, and provide a base for hand stitches that don't show.

Question 5: What does a fabric's 'grainline' on a pattern piece indicate, and why must it be followed?

Where to place buttons
The direction parallel to the selvage so the piece hangs and wears correctly (Correct answer)
The location of the hem
The cutting order of pieces

Correct answer: The direction parallel to the selvage so the piece hangs and wears correctly

The grainline arrow must run parallel to the selvage so the finished piece hangs straight and resists distortion.

Question 6: What is the standard seam allowance used in most tailored garments?

2 inches (5 cm)
5/8 inch (1.5 cm) (Correct answer)
1/4 inch (6 mm)
1 inch (2.5 cm)

Correct answer: 5/8 inch (1.5 cm)

The standard seam allowance in tailoring is 5/8 inch (1.5 cm), which provides enough fabric to sew a secure seam while still allowing for fitting adjustments.

Question 7: In trouser construction, what is the 'crotch curve' and why is its shape important?

The curve of the waistband at the side seams
The curved seam joining the front and back trouser panels; its shape affects comfort and silhouette (Correct answer)
The crease line pressed into the front of the trouser leg
The topstitching on the waistband of the trousers

Correct answer: The curved seam joining the front and back trouser panels; its shape affects comfort and silhouette

The crotch curve is the curved seam joining the front and back trouser pieces; its depth and shape directly affect how the trousers sit, the comfort of the seat, and the overall silhouette.

Question 8: What is the primary purpose of pressing seams open in tailoring?

To make seams more durable against stress
To prevent the raw edges from fraying
To reduce bulk and create a flat, professional finish (Correct answer)
To add structure and stiffness to the garment

Correct answer: To reduce bulk and create a flat, professional finish

Pressing seams open distributes fabric bulk evenly on both sides, resulting in a flatter, more professional appearance.

Question 9: When a lining in a jacket tears away from the hem, what is the repair technique?

Fuse the lining to the jacket with iron-on tape
Re-slipstitch the lining hem back to the jacket hem allowance by hand (Correct answer)
Machine-stitch the lining from the right side
Replace the entire lining

Correct answer: Re-slipstitch the lining hem back to the jacket hem allowance by hand

When a lining detaches at the hem, re-slipstitching the lining hem back to the jacket hem allowance by hand is the correct, invisible repair technique.

Question 10: What should a tailor always document when a client brings in a garment for alteration?

The fabric composition listed on the care label
The client's phone number only
The client's name, the garment description, the requested alteration, and the agreed price (Correct answer)
Only the garment's brand and purchase date

Correct answer: The client's name, the garment description, the requested alteration, and the agreed price

A complete alteration ticket must record the client's name, a description of the garment, the specific alterations requested, the agreed price, and the promised completion date.

Question 11: When training on a serger/overlock machine, what safety point is critical?

Speed doesn't matter
It cannot cause injury
Cutting blades are exposed, so keep fingers away while feeding (Correct answer)
Threading order is irrelevant

Correct answer: Cutting blades are exposed, so keep fingers away while feeding

The serger's cutting blade can injure fingers, so hands must stay clear.

Question 12: This tool is used to cut designs with 5" or longer blades.

Cutter
Trimmer
Shears
Scissor (Correct answer)

Correct answer: Scissor

Scissors are versatile cutting tools commonly used in tailoring for various tasks, including cutting patterns, trimming threads, and making small cuts in fabric. While shears are typically longer and used for cutting fabric, scissors often have blades 5 inches or longer and are essential for more detailed or general cutting needs.

Question 13: How is a trouser hem typically lengthened when there is enough original hem allowance?

New fabric is added to the bottom of the trouser
The waistband is raised to add length
The original hem is let down, pressed, and re-hemmed at the new length (Correct answer)
The crotch seam is lowered to add length

Correct answer: The original hem is let down, pressed, and re-hemmed at the new length

When there is sufficient hem allowance, the original hem is released, the crease is removed with steam, and the trouser is re-hemmed at the new longer length.

Question 14: What is the purpose of 'felling' the lining in a jacket?

Pressing the lining with a damp cloth to set its shape
Hand stitching the lining to the jacket hem edge so the stitches are invisible on both sides (Correct answer)
Cutting the lining to match the outer fabric pattern
Machine stitching the lining to the facing along all edges

Correct answer: Hand stitching the lining to the jacket hem edge so the stitches are invisible on both sides

Felling is a hand-sewing technique that attaches the lining hem with blind stitches invisible on the exterior of the jacket.

Question 15: What is a 'fitting toile'?

A pattern-making ruler used for curves
A type of printed cotton fabric
A French term for the finished garment
A test version of a garment made to check proportions and fit (Correct answer)

Correct answer: A test version of a garment made to check proportions and fit

A fitting toile is a test version of a garment made in inexpensive fabric to check and adjust fit before making the final version.

Question 16: What is a 'Neapolitan shoulder' in tailoring?

A soft, unpadded shoulder with a slightly rippled sleeve head for a natural silhouette (Correct answer)
A rope-like extended shoulder pad popular in Italian fashion
A rolled shoulder seam used on casual sports jackets
A heavily padded square shoulder used in American power suits

Correct answer: A soft, unpadded shoulder with a slightly rippled sleeve head for a natural silhouette

The Neapolitan shoulder is a distinctive soft-structured shoulder with a hand-sewn, slightly ruffled sleeve head giving a relaxed look.

Question 17: A tailor measuring a client for trousers records the 'inseam.' This measurement is taken from:

The waist to the floor on the outside of the leg
Around the fullest part of the hip
The crotch to the desired hem along the inner leg (Correct answer)
Across the back from shoulder to shoulder

Correct answer: The crotch to the desired hem along the inner leg

The inseam runs along the inner leg from the crotch seam down to the trouser hem.

Question 18: Which of the following does NOT qualify as a sort of machine stitch?

Zigzag Stitch
Satin Stitch (Correct answer)
Buttonhole Stitch
Lockstitch

Correct answer: Satin Stitch

Satin stitch is a type of embroidery stitch used to create a smooth, solid area of color or texture, often for decorative purposes. It is not considered a basic machine stitch for garment construction, unlike the lockstitch (standard straight stitch), zigzag stitch (for finishing edges or stretch fabrics), or buttonhole stitch (for creating buttonholes).

Question 19: What is the recommended way to mark darts and dots transferred from a pattern onto delicate fabric?

A hot iron crease
Cut small notches through both layers
Tailor's tacks or chalk that brush or wash out (Correct answer)
Permanent ink pen

Correct answer: Tailor's tacks or chalk that brush or wash out

Tailor's tacks and removable chalk transfer marks without permanently damaging or staining delicate cloth.

Question 20: What is a 'tack' in garment repair and alteration work?

A long basting stitch for fitting
A permanent topstitch for structural reinforcement
A small stitch used to hold layers of fabric together in a specific position (Correct answer)
A mark made with tailor's chalk

Correct answer: A small stitch used to hold layers of fabric together in a specific position

A tack is one or more small hand stitches used to lightly hold fabric layers together in a particular position without them being seen from the right side.

Question 21: Under US consumer protection law, what must a tailor do if a garment is damaged while in the shop?

Return the garment without explanation
Refuse to release the garment until the client signs a waiver
Quietly repair the damage and say nothing
Notify the client promptly and negotiate fair compensation for the damage (Correct answer)

Correct answer: Notify the client promptly and negotiate fair compensation for the damage

Consumer protection principles and professional ethics require the tailor to notify the client immediately if a garment is damaged while in their care and to offer fair compensation.

Question 22: What technique is used to press open seams in thick wool suit fabric without creating shine or imprints?

Iron directly on the wool with high heat
Use a cold iron with heavy pressure
Use a clapper and press cloth with burst steam (Correct answer)
Press only from the right side without a cloth

Correct answer: Use a clapper and press cloth with burst steam

A wooden clapper is used with a press cloth and burst steam — the clapper absorbs steam and applies firm pressure to flatten seams without shine or fabric damage.

Question 23: When pressing interfaced areas such as cuffs and collars, what is the correct sequence?

Press the right side first, then the wrong/interfaced side
Press the interfaced side first, then finish from the right side with a pressing cloth (Correct answer)
Press only from the right side with a damp cloth throughout
Avoid pressing interfaced areas entirely to prevent distortion or bubbling

Correct answer: Press the interfaced side first, then finish from the right side with a pressing cloth

Pressing the interfaced side first activates and bonds the interfacing properly; a final press from the right side using a pressing cloth then gives a smooth, finished surface.

Question 24: What distinguishes bespoke tailoring from made-to-measure tailoring?

Bespoke uses a unique pattern drafted from scratch for each client; made-to-measure adjusts an existing block (Correct answer)
Bespoke uses factory machinery while made-to-measure is entirely hand-sewn
Bespoke garments are always priced lower because fewer materials are used
Bespoke only refers to women's clothing while made-to-measure covers menswear

Correct answer: Bespoke uses a unique pattern drafted from scratch for each client; made-to-measure adjusts an existing block

True bespoke tailoring creates an individual pattern for each client and involves multiple fittings, while made-to-measure modifies a standard template.

Question 25: What is a 'welt pocket' in tailoring?

A patch pocket stitched on the outside of the garment
A kangaroo-style pocket on the front of the garment
A pocket opening finished with folded strips of fabric forming a slit (Correct answer)
A hidden pocket sewn into the side seam

Correct answer: A pocket opening finished with folded strips of fabric forming a slit

A welt pocket is formed by a slit opening finished with one or two narrow fabric strips (welts) that frame the pocket opening neatly.

Question 26: What is the significance of offering a 'satisfaction guarantee' in a tailor business?

It legally protects the tailor from all liability claims
It builds client trust and reduces risk aversion for new customers considering custom work (Correct answer)
It eliminates the need for client fittings
It requires the tailor to refund all dissatisfied clients unconditionally

Correct answer: It builds client trust and reduces risk aversion for new customers considering custom work

A satisfaction guarantee signals to clients that the tailor stands behind the quality of the work, building trust and making potential new clients more comfortable committing to custom or alteration work.

Question 27: Which natural fiber is known for getting stronger when wet, making it suitable for summer suiting?

Cotton
Silk
Linen (Correct answer)
Wool

Correct answer: Linen

Linen fibers actually gain tensile strength when wet, and the fabric is highly breathable for warm weather.

Question 28: Which fabric characteristic is described by the term 'hand'?

The thread count of the fabric
The fabric's color fastness
The fabric's tensile strength
How the fabric feels to the touch (Correct answer)

Correct answer: How the fabric feels to the touch

The 'hand' of a fabric refers to its tactile qualities such as softness, drape, stiffness, and texture.

Question 29: Which hand stitch is best for an invisible hem on a tailored skirt?

Running stitch through all layers
Backstitch
Whipstitch on the right side
Catch stitch or blind hem stitch catching only a thread of the outer fabric (Correct answer)

Correct answer: Catch stitch or blind hem stitch catching only a thread of the outer fabric

A catch or blind hem stitch picks up only a single thread of the garment face so the hem is invisible from the right side.

Question 30: What is the purpose of a 'fitting receipt' given to a client at drop-off?

To certify that the garment passed a quality inspection
To serve as proof that the client left the garment and to detail the agreed work and price (Correct answer)
To record the client's credit card payment information
To list the care instructions for the client's fabric

Correct answer: To serve as proof that the client left the garment and to detail the agreed work and price

A fitting receipt documents that the client left the garment with the tailor, itemizes the agreed alterations, confirms the price, and states the pickup date, protecting both parties.
