Fit Guide
- FITTED: Trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably under outer layers.
- REGULAR: Classic fit is cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably under our regular and relaxed fit shells.
- RELAXED: This fit is cut loosely through the chest, waist, hip, and thigh. Relaxed without sacrificing structure and clean lines, it offers comfort and freedom of movement with a more casual look.
- OVERSIZED: The most generous fit is cut loosely throughout the entire body. Dropped shoulders and wide sleeves provide freedom of movement while offering drape and structure for a contemporary look.
