Popflex pink & blue floral romper sz 8

This Popflex pink & blue floral romper is so cute and I only wore it maybe once or twice. The zipper is a bit messed up and it's hard to zip up (shown in last pic). It can be done but it's a little tough. Maybe this can be fixed? It's a size 8 and comes with the built in bra pads. It's very stretchy and comfy. Lying flat, it measures about 15" across the bust, 15" across the waist, and about 32" from shoulder to bottom hem.
