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

Comfort and flexibility combine in our CUUTTI two-way zipper baby onesie! Made in the EU from OEKO-TEX® 100 certified European cotton with a hint of elastane for a stretchy fit, keeping your baby cozy as they grow!

  • Convenient two-way zipper for quick and easy diaper changes
  • Fold-over feet to keep tiny toes warm and comfy
  • Fold-over mitts (up to 6 months) to protect your baby’s sensitive skin from scratches
  • No neck labels for extra comfort!

The bodysuit pairs perfectly with our CUUTTI SNAP-ON waterproof bib (that you can buy separately), which easily attaches to the neckline. This bib protects their delicate skin from drooling and is available in perfectly matching shades. The bib is a universal size and fits all CUUTTI onesies and bodysuits.
