Fitting tightly in the area covering the buttocks.
tight-assed: garment that pulls too hard across the rear
A garment is tight-assed when the fabric across the buttocks sits uncomfortably snug, restricting movement and often pulling or puckering. This defect appears most often in trousers, jeans, and close-fitting skirts, where the seams or fabric panels do not have enough ease or stretch to accommodate the wearer's body shape. The problem manifests as visible tension lines radiating outward from the seat, a sensation of the fabric being pulled upward, or visible creasing and distortion across that area.
The root causes vary by garment type and fit. In woven trousers, the issue usually stems from insufficient rise, inseam length that forces the garment too high into the crotch and seat, or a back waist measurement that is too small relative to the back hip width. In knit goods, inadequate stretch recovery in the fabric or a pattern cut that assumes a flatter rear profile can create the same problem. Denim manufacturers often experience this when indigo fabric shrinks unevenly or when the five-pocket configuration is poorly graded across size ranges.
Quality assurance teams catch tight-assed garments through wear testing and fit grading. A tester will walk, sit, bend, and squat in the sample while an inspector watches for seam strain, fabric distortion, and restricted hip and thigh mobility. Industrial fit models come in different body types precisely to prevent this kind of systematic misfit. The defect also emerges during retail returns, where customer photos and complaints flag patterns that need immediate revision.
Correcting a tight-assed fit requires pattern adjustments rather than simple sizing tweaks. Pattern makers may increase the back hip width, raise the back waist, deepen the rise, or adjust the seat curve (the amount of fabric ease built into the back panel). Stretch content helps disguise marginal fits in casual wear, but cannot fully compensate for bad pattern geometry. In premium tailoring, the term rarely applies because individual measurement and bespoke alteration eliminate the problem before the garment reaches the customer.
