Green leaf jumpsuit

Purchased from another posher, but unfortunately its too small for me. Im a size 8 and the jumpsuit is a size 6. It is so gorgeous, I wish it fit me :(.. has a zip closure in the back. Never worn but unfortunately I removed the tag before trying it on because I expected it to fit (the posher I purchased it from said that even though it’s a size 6, it would best fit a size 8, which wasn’t the case).
