Fit descriptions

All garments are designed and fitted to suit their intended end use. See below for a general description of our fit categories:

Slim

A streamlined silhouette. Cut trim following the contours of the body. Expertly placed articulation of seams and the use of stretch fabric ensure maximum freedom of movement in these close-fitting items.

Regular

Neither slim nor loose. Regular fit items are the perfect balance of form fit and ease of movement.

Relaxed

Our more generous fit. Cut loosely through the body allowing for ease of movement and additional layering.
