Nicole goes sexy whilst Tulisa gives her look a girly twist

Last night's shock exit of young (and impeccably stylish!) Ella Henderson made our hearts sink but the black dress-off from the two female judges added a little cheer to the evening. The ever-sexy Nicole stunned us in a revealing black cut-out leather dress whilst Tulisa showed up in a totally different style wearing an elegant and feminine black lace number. When sexiness and elegance are both presented in such a perfect way, which LBD gets your vote?

The black leather dress Nicole chose featured a moody maxi skirt and sleeveless leather top and an eye-popping belly-baring cut-out with several straps around the 34-year-old singer's toned waist and smooth décolletage. With her petite frame accentuated in the skin-tight leather bustier, the ex-Pussycat Doll finished her sexy look by showing some leg via the rather high side leg-split. With straightened hair and on-trend pewter leather heels Nicole was the epitome of sexy, sophisticated dressing. Tulisa however went for a very feminine and delicate black lace dress. The mini dress designed with a fitted corset and black lace cap sleeves hugged the 24-year-old's body in all right places and enhanced her best assets in a understated way. Made of shimmering satin fabric the dress was covered with exquisite black lace that spread from the sweetheart lace bustier all over the frock with a lace hem finish. Teamed with diamante accessories and matte black heels Tulisa looked elegant and fresh whilst she added a touch of cuteness with a smart side bun and bright pink lips.
