Ordered Thursday Morning and Received Friday evening (overnight shipping). I am 5'1/5'2 , 140-145 lbs and I ordered a small. It fits perfectly! I have thick thighs and big booty, material is stretchy enough and not tight but fitted enough to fit my curves. I assume this size runs big because I normally wear medium tops and large shorts/skirts. Texture is amazing! Great dress ♥️ definitely recommend! I do wish the gold went all the way around but dress is still beautiful.
