Never worn Michael Kors black sequin party dress. Can be worn alone as mini dress or with tights/leggings. XS fits size 2-4, possibly 6 depending on bust size. I am 34D and the dress zips no problem. 3/4 sleeves and ruffle skirt. Fun LBD that could pass for cocktail dress without being over the top. Dress does not have tags - but I bought it new and never ended up wearing it. In great condition. No defects or odors.
