Home / Lil Boop Boop Size Guide - Two Way Zipper Onesie

Our Onesies are made to fit larger and the spandex in the fabric gives it a lot of stretch thereby allowing for longer use. The cuffs on the feet allow for more length as well. The weight scale is approximate, however, if you have any doubts choose by height.
