Yellow floral romper

This is a light yellow romper with a floral design. The straps criss cross on the back... and then buttons right behind the neck. The back droops down a little and opens up to expose your back (shows in picture). I bought this from a fellow PFF and it’s too puffy & big on me as you can see in the pics. Has a lot of breathing room. ***Tag says XS but fits S-M!!*** Laced on bottom side of shorts. Gently used but in excellent condition! Willing to negotiate on price with reasonable offers
