Dress was only worn once!!! Like new. Size medium. I would say it fits true to size. The weekend is here and its time to celebrate in the You Should Be Dancing Mini Dress in Black. Featuring thin, adjustable straps, bust underwire, boning in bodice, invisible zipper centre back, lined mesh fabric and diamanté embellishment. We love this paired with perspex heels and silver accessories and get ready to dance the night away! - 90% Polyester 10% Elastane
