Fit Guide

At teeny tiny couture we strive to make our products fit true to size. This means, if a baby is of average size for their age, they should fit in the corresponding age range onesie. 

When in doubt, we always recommend you go a size larger because babies are constantly growing and that larger size onesie will fit before you know it!

When purchasing a gift for a new baby, we recommend the 3-6 month size. We've done the leg work for you and surveyed new parents and this is the size they have consistently requested for baby gifts.
