NWOT Dorothy Perkins blush pink & black Cocktail Dress w/jewel neckline Size 16

NWOT Dorothy Perkins blush pink and black polyester/elastane Scoop Neck Knee-Length Chiffon top Cocktail Dress with jeweled faux diamond neckline in front. Looser blush pink chiffon on upper part of dress with tank lining underneath with adjustable straps. In certain light the top looks more like a peach color to me. Zipper closure down the back, top button closure at back of neck (comes with two additional buttons attached to inside tag). Chiffon opening in the upper back for zipper. Beautiful dress, never worn, tag has been removed, does have tiny spot near top right shoulder, and tiny thread ball on top of back right shoulder (please see pictures). Size 20 UK which is a 16 in US.
