NWOT - So sad it didn’t work out for my little one to wear this but hopefully yours can! Serendipity is part of Shrimp & Grits kids line and their clothes are so soft and hold up very well. This bubble has an open cross back straps. Snap button crotch closure. Buttons on the straps work but the detail ones on the body are just for looks. This does not have an extra hole to use at a different length. The colorful boats on the pretty blue background make this such a cute spring/summer outfit for boy or girl! Size 18m
