Designed to fit snugly along the curves of the body.
Slim fit
Designed with a slender silhouette (for jackets, designed to allow for a thin inner layer).
Regular fit
A moderately fitting design that is neither too slim nor too loose (for jackets, designed with enough room to wear a thick inner layer). For men's pants, the regular fit is slightly narrower through the thighs, lower legs, and hem.
Relaxed fit
Designed to drape loosely over the body. For men's pants, the relaxed fit is roomy through the hips, thighs, lower legs, and hem.
