One-Pieces Size Chart

CUUTTI clothes are designed for a snug fit, with long legs and sleeves that can be rolled up to extend their lifespan. Generally, you should choose the size based on your child's height.

Since children grow at different rates and clothing models vary, if you're unsure between two sizes, we recommend choosing the larger one.

AGE SIZE CM
0-3M 56-62
3-6M 62-68
6-9M 68-74
9-12M 74-80
12-18M 80-86
