The onesie is cut roomy on purpose — it is loungewear, not a suit. Between two sizes? Take the smaller one for a closer fit, the larger one for extra room over pajamas.
| Size | Height | Fit |
|---|---|---|
| S | 5'0" – 5'4" | Relaxed |
| M | 5'4" – 5'8" | Relaxed |
| L | 5'8" – 6'0" | Roomy |
| XL | 6'0" – 6'3" | Roomy |
Still unsure about sizing? Just remember: there is no such thing as too much monster.
