Finding your size
The quick way — order by age. Between sizes? Size up. Organic cotton softens beautifully with washing.
| Size | Age |
|---|---|
| XXS | 3-4 |
| XS | 4-5 |
| S | 6-7 |
| M | 8-9 |
| L | 10-12 |
| XL | 14-16 |
The sure way — measure a shirt that fits. Lay it flat: chest armpit to armpit, length shoulder seam to hem.
| Size | Chest | Length |
|---|---|---|
| XXS | 12.5" | 15.5" |
| XS | 13.5" | 16.5" |
| S | 14.5" | 17.5" |
| M | 15.5" | 19" |
| L | 16.5" | 20" |
| XL | 17.5" | 21.5" |
