Primark Atmosphere Blue Sleeveless Dress

Beautiful deep or royal blue sleeveless dress purchased from Primark in the UK. Thicker soft fabric, almost like neoprene but not. Zipper on the back. Approximately knee length on me and I'm 5'6. Size is a UK 6, which normally fits like 0-2 US, but this one fits bigger, especially in the waist, so could fit up to 4 US or a size small. Very versatile, could be worn out casually, for parties, or for work with a cardigan or blazer. Was a gift so missing the price at the bottom of the tag.
