Striped romper- fits like a 6

So cute for summer! Striped romper. Boutique sizing- this fits like a 6. The fabric is medium weight. The romper has a maxi-skirt overlay with a (mostly) open back with cross crossing straps. Purchased from another posher’s boutique, but it’s a little too tight for me (I’m a true 8). Romper, jumpsuit, open back
