Size Guide
Every BETISA tee is cut oversized, with dropped shoulders and a relaxed body. It is meant to sit away from you rather than against you.
Measurements
These are garment measurements — the piece itself laid flat, not body measurements.
| BODY LENGTH | SLEEVE LENGTH | CHEST | |
| S | 28.7 in (73 cm) | 9.4 in (24 cm) | 39 in (99 cm) |
| M | 29.5 in (75 cm) | 9.6 in (24.5 cm) | 43 in (109 cm) |
| L | 30.3 in (77 cm) | 9.8 in (25 cm) | 47 in (119 cm) |
| XL | 31.5 in (80 cm) | 10.0 in (25.5 cm) | 51 in (130 cm) |
| 2XL | 32.5 in (82.5 cm) | 10.2 in (26 cm) | 55 in (140 cm) |
Measurements may vary by up to half an inch. Each piece is finished individually.
The most reliable way to choose
Find a t-shirt you already own and like the fit of. Lay it flat, smooth out the wrinkles, and measure it.
Chest: measure straight across, from one underarm seam to the other, then double that number.
Body length: measure from the highest point of the shoulder straight down to the hem.
Compare those two numbers to the table above. This works far better than guessing from your usual size, because "medium" means something different at every brand.
If you're between sizes
Take the smaller size. Our fit is already generous, and the larger option will read as noticeably loose rather than relaxed.
If you want a different look
The intended fit: your usual size.
Closer to the body: size down.
Deliberately loose: size up — but check the body length first, because it grows with each size and can end up longer than you expect.
