White summer dress floral flowy backless

This is the cutest, most comfortable summer dress and it has no flaws. My butt is big and it feels like it’s cutting it a little close length wise for me now. I think someone a little smaller than me in the boobs or butt or height department would fit this perfectly. It is so flattering and well made. It is in great shape and is easy to take care of. I am 140 lbs 5’3’’ D cup size
