Floral One Shoulder Asymmetrical Hem Dress Size S

This is a stunning dress that I bought to wear to dinner on vacation, but it is too big on me! It has a side zip and looks like it needs to be taken in at the side. It's wider in the chest area than it should be. I couldn't return it since it was outside the return window. Pretty subtle colors and a flattering fit. It's just too big on me. Runs like a medium, to be honest. Brand New in Shein packaging! Size S/4 S H E I N
