Pleat (G):
A double or multiple fold in a garment held by stitching the top or side. Pleats add more volume to a pant, contributing to a roomier fit through the thigh and seat.
Fly (H):
The fly is an opening on the crotch area of pants and trousers, closed by a zipper or buttons.
Dart (I):
Darts are folds (tucks coming to a point) sewn into fabric to take in ease and provide shape to a garment.
Gusset (J):
A second layer of cloth sewn into a piece of clothing to make it larger, stronger, or more comfortable, commonly found on pants reinforcing the crotch area.
Hems (K):
A hem is the finished edge of a piece of cloth folded and sewn to prevent unraveling of the fabric. Hems adjust the length of the piece in garments, such as at the end of the sleeve or the ankle opening of a pant leg.
Wale (L):
In corduroy fabric the wale refers to the ribs or cords that run lengthwise through the fabric. The number of wales per inch indicates the fabric's fineness. A thinner wale (or higher wale count) makes for a finer and lighter weight fabric, whereas a wider wale (or smaller wale count) results in a heavier weight, more substantial fabric. Wide wale corduroys are commonly used for pants while thin corduroy fabrics are more common for shirts and tops.
Yoke (M):
The V-shaped section at the back of jeans between the waistband and the leg panels. The yoke gives a curvature to the seat contributing to a more comfortable fit on the body.
Waistband (N):
Waistbands are the finishing element at the waistline of a pair of pants and prevent them from falling down. Standard waistbands on pants are made of the same fabric as the rest of the pant with belt loops to accommodate sizing preferences. Other common waistbands include elasticated waistbands and waistbands with adjustable webbing belts.
