Classic Little Black Dress, Size "P"

Tag says the size is "P," but I'm listing as 0P since P isn't an option in listing here. Perfect condition! 34.5 inches from top of shoulder strap to bottom of the dress (falls just above my knees and I'm 5'2"). 13 inches across the bust, 15 inches across the widest part of the hips (my hips measure 33 inches and this dress fits great, but it has some stretch). This dress does not have a zipper-- simply slip on. Cute ruffle at the bottom. It's truly beautiful, great worn as is or with a jacket.
