Find Your Fit

BIACAS tees are cut oversized and drop-shoulder by design. If you're between sizes, size down for a relaxed fit or stay true to size for a more oversized look.

How to Measure

Chest: Measure around the fullest part of your chest, keeping the tape horizontal.
Length: Measure from the highest point of the shoulder down to the hem.
Shoulder: Measure from the edge of one shoulder seam to the other across the back.

Fit Notes

The BIACAS Essential is designed to be worn oversized. The drop shoulder sits below your natural shoulder point — this is intentional, not a sizing error.

Most customers find their regular size works perfectly. If you prefer a more fitted oversized look, size down by one.
