Domain 1: Fabrics
Question 1
Replacement ribbing for a close-fitting cuff must extend at least 30% across its width and show no more than 3% residual growth, measured against its original relaxed length. Under the same test load, 100 mm marked spans give these results: sample X reaches 140 mm and measures 106 mm after 10 minutes of rest; sample Y reaches 135 mm and measures 101 mm after the same rest. Which selection meets the cuff specification?
Show answer & explanation
Correct answer: D - Y only; its extension is 35% and its residual growth is 1%.
Question 2
Identify the cause of puckering from this bench test: a densely woven seam remains puckered when the needle and bobbin threads are cut at every stitch but the loops are left in place. Removing the loops lets both plies lie flat and equal in length. The sample has not been pressed or laundered.
Show answer & explanation
Correct answer: A - Structural jamming of fabric yarns at the stitch line.
Domain 2: Alteration Techniques
Question 3
The hem of a relined jacket curls upward when the lining is attached. With the lining released only at the hem, the shell drops to the agreed length and the back vent hangs correctly. The lining has ample width but is taut from shoulder to hem. Where should the correction be made?
Show answer & explanation
Correct answer: C - Restore lengthwise movement allowance in the lining.
Question 4
A shortened shirt sleeve has the correct wrist fit, but the hand catches at the top of the sleeve opening even with the nonstretch cuff fully unbuttoned. Which reconstruction restores access without enlarging the cuff?
Show answer & explanation
Correct answer: B - Lengthen the usable placket opening, then reform the pleats and reattach the cuff.
Question 5
A woven skirt measures 108 cm around the finished hip line; the client's hip measurement at that level is 100 cm. A fitting confirms that 4 cm of total ease gives the intended silhouette and comfortable sitting. The agreed reduction will be divided equally between the two plain side seams, with the front and back altered equally. At the hip line, how far should each new stitching line move inward from the old one?
Show answer & explanation
Correct answer: D - 1.0 cm
Domain 3: Alteration Fit
Question 6
A two-piece jacket sleeve hangs smoothly when the client deliberately holds the arm farther back, but develops diagonal twisting folds when the arm returns to its natural resting position. Sleeve length, upper-arm room and shoulder width are satisfactory; releasing the cuff lining makes no difference. The fitting trial most likely to resolve the twist is:
Show answer & explanation
Correct answer: A - Rotate the sleeve within the armhole to match the resting arm.
Question 7
The crotch of a pair of elastic-waist trousers hangs too low. When the fitter holds the trousers at the agreed waist position, the crotch and leg hang become satisfactory; on release, the waistband slips down. The elastic remains stretched after being pulled. Which repair addresses the cause without changing the successful fit?
Show answer & explanation
Correct answer: D - Replace the failed elastic and refit its holding tension at the waist.
Domain 4: Alteration Overview
Question 8
On a tailored jacket, the proposed shorter cuff edge would pass through an already cut working buttonhole. The client wants the existing cuff and buttonhole arrangement preserved. You are experienced in resetting sleeves, but have not yet assessed whether this sleeve can be shortened at the head. How should the request be handled?
Show answer & explanation
Correct answer: B - Assess a sleeve-head alteration before agreeing on the method and price.
Question 9
At a bridal fitting, a strapless gown's skirt is pinned to length before the bodice is adjusted. The bodice alteration then raises the skirt's support point, and the bias-cut chiffon overlay hangs unevenly relative to the underlying skirt. Both layers are intended to fall independently. Which finishing sequence avoids committing to a misleading hemline?
Show answer & explanation
Correct answer: A - Confirm bodice fit, let the skirt settle, and level the layers separately.
Domain 5: Professional Practices
Question 10
A client authorizes trouser hemming at a fixed price. During intake, you also identify a worn fly zipper that still operates; it does not affect the hemming. The written order requires separate approval for additional work. The client cannot be reached before the scheduled collection. Which course respects the existing agreement?
Show answer & explanation
Correct answer: C - Complete the authorized hem and disclose the zipper condition at collection.
