I ordered this dress for a wedding, and went with a medium, just Incase (my measurements added up to a small, but decided to go for the medium as I could always take it in). I could not zip the medium up, it was about 2” off across the board. For reference my measurements are: 34-27-37 and I normally wear a small. Now I have to pay for shipping to return this, and dressless for the wedding. Not happy!
