Size Chart
Every body moves through the world differently, and our sizing is built around that, not against it. Most MAS pieces are cut to be relaxed and flowing rather than fitted — so before you reach for your usual size, take a minute to read how ours actually fits.
How to Measure Yourself
Use a soft measuring tape, worn over light clothing or against bare skin.
- Chest: measure around the fullest part of your bust, tape level all the way around.
- Waist: measure around your natural waistline — the narrowest point, usually just above your belly button.
- Hips: measure around the fullest part of your hips and glutes.
If you're between two sizes: size down from your measurements for a fit closer to what you're used to in standard clothing, or size up (or stay true to your measurements) to lean into the relaxed, oversized drape our pieces are designed for. Neither is "wrong" — it's a matter of how you want the piece to sit.

A Note on Fit
Most MAS pieces are designed to be oversized rather than fitted — that's a deliberate choice, not an inconsistency between styles. Each product page includes its own fit notes under "Cut & Style" and "Why It Will Look Good On You," so check there for guidance specific to that piece.
