Size Guide
At LOSMIOS we don't sell sizes, we sell the fit. This guide has the real measurements for every garment type in our catalog, how to measure yourself at home with a tape measure (or a piece of string and a ruler), and the international size equivalents. Still not sure after reading it? Use the "Don't know your size? Find it in 15 sec" button next to the size selector on any product.
How to measure yourself in 2 minutes
- Chest circumference: wrap the tape around the widest part of your chest, under your arms, keeping it level. Don't pull it tight — just snug against your body.
- Height: standing against a wall, no shoes.
- Weight: whatever your scale says — no need to fast or do anything special.
With those three measurements you can read the tables below, or let the widget do the math for you.
T-shirt — regular fit
Our true-to-size cut: not tight, not oversized. If your measurement falls right between two sizes and you like it looser, size up.
| Size | Chest circumference (cm) | Intl. equivalent |
|---|---|---|
| S | 92–96 | US/EU S |
| M | 96–100 | US/EU M |
| L | 100–106 | US/EU L |
| XL | 106–112 | US/EU XL |
| 2XL | 112–118 | US/EU XXL |
| 3XL | 118–124 | US/EU XXXL |
Hoodie
Hoodies run a bit roomier than our t-shirts by design — that's the cut, not a reason to size down.
| Size | Chest circumference (cm) | Intl. equivalent |
|---|---|---|
| S | 98–104 | US/EU S |
| M | 104–110 | US/EU M |
| L | 110–118 | US/EU L |
| XL | 118–126 | US/EU XL |
| 2XL | 126–134 | US/EU XXL |
Sweater
Between the t-shirt and the hoodie in roominess — a bit more space than the regular tee, without the hoodie's bulk.
| Size | Chest circumference (cm) | Intl. equivalent |
|---|---|---|
| S | 95–100 | US/EU S |
| M | 100–105 | US/EU M |
| L | 105–112 | US/EU L |
| XL | 112–119 | US/EU XL |
| 2XL | 119–126 | US/EU XXL |
Sleeveless
Narrower shoulder cut with an open armhole — use your regular chest measurement, no need to add extra room.
| Size | Chest circumference (cm) | Intl. equivalent |
|---|---|---|
| S | 90–94 | US/EU S |
| M | 94–98 | US/EU M |
| L | 98–104 | US/EU L |
| XL | 104–110 | US/EU XL |
| 2XL | 110–116 | US/EU XXL |
Cap
One size, adjustable with a back strap. Approximate head circumference: 54–61 cm.
Between two sizes? If you like it snug, go with the smaller size. If you like it looser, size up. When in doubt, most of our customers go with the larger of the two.
