H&M romper in a lemon print size 4 with adjustable straps (by buttons) and side zipper. I believe this romper fits somewhat small, measured the waist with the zipper up and is 12.75in across in with no stretch at all so maybe use that as guide. Very cute with a white top. Please let me know if you have any additional questions. Callout: might need a couple of stitches on the back (5th picture), other than that in great condition.
