Sizing Guide


All measurements are taken flat, from seam to seam:

Small - Bust: 30" Waist: 26"
Medium - Bust: 34" Waist: 30"
Large - Bust: 38" Waist: 34"



Every mariana piece is designed with adjustability and comfort in mind—because our bodies shift, expand, soften, and change, even in a single day.

Lace-up closures at shoulder and back allow for an adjustable fit to better suit your body. If you’re between sizes, we recommend sizing down for a closer fit, or sizing up if you prefer a more relaxed feel.
