Size Guide

Finding the right fit shouldn’t feel like a guessing game.

Our swimwear is designed to move with your child, not restrict them, so you can focus on the fun, not constant outfit adjustments.

Bubby Buu Size Chart for Kids Swimwear

How to choose the right size

  • Fits true to size for most children
  • If between sizes, we recommend sizing up for longer wear
  • Designed with stretch to move comfortably with active kids
  • Cuffs and flexible fabric allow for a little extra growing room

Built for wriggles, growth spurts, and everything in between.

Real-life fit, not just measurements

Kids don’t stand still (literally ever), so we design with movement in mind.

Our pieces are made to stretch, bend, splash, and keep up, without digging in, riding up, or needing constant adjusting.

Because getting them dressed should be the easy part.
