Girls zip-up one-piece swimsuit

This suit is adorable! The ruffle detail is a nice touch. We REALLY appreciate the zipper, helps to get it on and off. I would say it runs a size small. My daughter is a 6-7 in Jcrew clothes and the swimsuit in the same size was TIGHT. 8 fit better and would've worked just fine, but she preferred a 10 for a looser, more comfortable fit.
