A gusset is a triangular or diamond-shaped piece of fabric inserted into a seam - adding room, strength, or shape at stress points like underarms and crotches.
Where Gussets Go
- Underarm - the classic gusset location: a diamond inserted at the underarm seam gives reaching room without a baggy body
- Crotch - in activewear and workwear, a gusset adds comfort and prevents the center seam from failing under stress
- Bags and gloves - gussets create three-dimensional shape, turning flat pieces into containers with depth
Why They Work
A gusset does two jobs at once: it adds fabric exactly where movement demands it, and it distributes stress across multiple seams instead of concentrating it on one. That's why a gusseted underarm outlasts a plain one, and why climbers, welders, and athletes all end up in gusseted garments. Usually cut on the bias for extra give, the gusset is small but mighty.
