She had earlier wowed fans in a sleek red dress as she took to the stage on The X Factor.

But, after a successful evening on the ITV show, Kelly Rowland messed things up on the fashion front when she left the television studios wearing a gaping pink dress which left her black bra entirely on show.

However, the 30-year-old singer looked delighted with her departure outfit choice, posing provocatively for the cameras in the less than attractive dress.

Earlier on the show, Kelly had shown off her figure in a form-fitted Todd Lynn dark red dress, teamed with Crisian & McCaffrey heels and Lorraine Schwartz jewellery.

Meanwhile, in a turn of tables on the fashion front, Tulisa Contostavlos was seen looking chic in a printed minidress as she left the studios, following an unfortunate outfit choice for the live show.

Tulisa had opted for a Halloween-style shredded leather dress and black heels which made her look as though she was trying too hard in comparison to Kelly's understated appearance.

No competition: Earlier in the evening, Kelly looked sleek in her dark red dress, while Tulisa missed the mark in her shredded leather gown

Her departure outfit, however, was more suited to her 23 years, looking more fresh and trendy than her stage look.

And it was a quick change for Tulisa, who then changed into a gold minidress as she visited London's G-A-Y nightclub to see her former act 2 Shoes perform.

Earlier this week, Tulisa took to her Twitter page to explain the reasons behind her bizarre one arm salute, which had been a cause of much amusement among viewers.

She wrote: 'Lol I know my ndubletts already know this but people keep askin y I throw up my arm on the XF,cus the tat is my trade mark The Female Boss.'

And Tulisa treated fans to another glimpse of the salute on last night's show, teaming her raised arm with a cheeky wink.

The majority of the X Factor acts looked happy with their performances as they left the studios following the live show.

Heading home: Kitty Brucknell looked happy with her performance, and waved to photographers as she went home

Excited: It seems Kitty may have finally impressed the judges after performing Bjork's It's Oh So Quiet

Kitty Brucknell, who divided viewers with her attention-grabbing performance of Bjork's It's Oh So Quiet, looked delighted, smiling and waving for photographers as she headed back to the Hertfordshire house in a coach.

But Frankie Cocozza, who has attracted criticism that it is his personality and not his voice that has got him this far in the competition, looked somewhat downcast following the judges' comments about his performance of Coldplay's The Scientist.

Sophie Habibis also got mixed comments after singing The Calling's Where Ever You Will Go, with Gary Barlow saying she is lacking the 'spark' he is looking for on the programme.

However, the 19-year-old London barmaid, who had complained earlier in the show that she was less famous than her competitors in the girls group, looked relatively happy as she headed back to the X Factor house after the show wearing a pretty cream dress and printed boots.

Despite their happy appearances, however, the contestants will no doubt be feeling nervous about who will be voted off the competition in tonight's show.

The X Factor is on ITV1 tonight at 8pm.
