Calvin Klein mini dress size 4 NWOT

Never worn white black and red orchid print Calvin Klein dress. Shorter than the blue dress shown. Or maybe I’m just taller. I’m 5’7 140lbs usually a 4-6 in dresses. This dress is a 4 and slightly loose on me, but just enough to be comfortable. Stretchy thicker material helps cover and body texture ;). Very comfortable dress. Listed as a 6 since it fits like a 6. But size is 4.
