Sully's Monster Cuddles Baby Romper Size Guide

Romper measurements are the best guide for choosing a size.

US Size Age Romper Length Bust
0–6M 0–6 Months 12.6" (32 cm) 17.3" (44 cm)
6–12M 6–12 Months 13.4" (34 cm) 18.1" (46 cm)
12–18M 12–18 Months 14.2" (36 cm) 18.9" (48 cm)
18–24M 18–24 Months 15.0" (38 cm) 19.7" (50 cm)
2T–3T 2–3 Years 15.8" (40 cm) 20.5" (52 cm)
💜 Fit Tip: Babies can vary quite a bit in size, so we recommend choosing primarily by the romper measurements rather than age alone. If your little monster is between sizes or you would like extra room for comfort and layering, sizing up is recommended.
