NWOT SHEIN Ruffle Trim Ruched Floral Dress

Elegant floral print, form-fitting summer dress. This is a medium and fits more like a small on the bottom. The bottom of the dress is not stretchy at all. I'm usually a medium but the bottom is way too tight for my butt. Never worn, just tried on once after purchase. Multicolor, V neck, puff sleeve, short sleeve, slim fit, chiffon, 100% polyester, non-stretch fabric.
