Every weekend Team LBD watch X Factor waiting for that one black dress that will steal the show. In recent weeks we've come to rely on Nicole Scherzinger to bring that LBD out of the bag but last night it was feisty judge Tulisa who showed her girly side in this black prom dress. The 50s style black dress featured a full skirt and tight strapless bustier bodice which nipped in her tiny waist and gave her all-black look a really playful edge. We love the subtle glitter effect of the fabric which made it the perfect Saturday night frock and with the addition of Tulisa's trademark bling: a gold chain belt and over-sized cocktail rings the singer made sure all eyes were on her. And thanks to Littleblackdress.co.uk you can copy Tulisa's naughty but nice look with Kate Fearnley's Buttercup dress (which comes in a variety of shades if black isn't your thing). This pretty party dress is a favourite in our office not least because it's super flattering and allows for accessory overload and more is more! Teamed with a pair of Bourne's dance-all-night high heels (we road-tested these beauties at an event last week and lasted all night long!) you'll be ready to take your own centre stage. Kate Fearnley Buttercup Dress in Black, £180, Byrogue Alice Knuckle Ring in Gold, £125, Bourne Laila Shoe in Black, £146. Shop all prom dresses here.
