Size guide
Measure your body and find the band you fall into. Between two sizes, we suggest sizing up, because sleepwear is more comfortable a little looser.
| Your measurement | S | M | L | XL | XXL | XXXL |
|---|---|---|---|---|---|---|
| Bust | 30.5–33.5 | 34–36.5 | 37–39.5 | 40–42.5 | 43–45.5 | 46–48.5 |
| Upper arm | 11–12 | 12.5–13 | 13.5–14 | 14.5–15 | 15.5–16 | 16.5–17 |
| US dress size | 4-6 | 8-10 | 12-14 | 16-18 | 20-22 | 24-26 |
| UK / AU | 8-10 | 12-14 | 16-18 | 20-22 | 24-26 | 28-30 |
| EU | 34-36 | 38-40 | 42-44 | 46-48 | 50-52 | 54-56 |
Body measurements, in inches. Dress and international sizes are size labels, so they do not change with the unit switch.
