But this occasion, no garment, however outrageous, could have drawn attention away from Cheryl Cole's alarmingly oversized lips.
The X Factor star's mouth looked unusually plump as she arrived in London yesterday - prompting speculation that she has used Collagen injections.
Representatives of the Girls Aloud singer denied this was the case, saying 'she has definitely not'.
But Miss Cole was seen trying to cover up her mouth with her hand as she walked through the airport.
When she did reveal her face, her normally slim lips appeared to have swelled somewhat and even led to comparisons with Leslie Ash's 'trout pout'
She covered her mouth at one point and seemed to have a bigger lips than normal 
Cheryl, seen here last July, sporting her usual lookCollagen is a natural protein which can be injected into the lips as a way of making them fuller. Implants are becoming increasingly common with patients as it is a relatively cheap and simple procedure.
It was in November last year that the 26-year-old was accused of misleading her fans after it was revealed that she had starred in a number of advertisements for shampoo company L'Oreal, despite failing to admit she used hair extensions.
In the past the singer has revealed she is not against cosmetic surgery. But she said that she would always be honest over whether she had indulged.
She also said she has no issues with others going under the knife if it makes them more confident admitting: 'I've got nothing against cosmetic surgery.
'I mean, if someone hasn't got any boobs and having them done is going to make them a happier, more confident person, then go for it.
'I wouldn't deny it if I had cosmetic surgery. I wouldn't just come out with big boobs and say, 'No, I haven't had an operation!'
And Cheryl believes that imperfections are sexy on a person, as if everybody was flawless, it wouldn't be realistic.
'I think imperfections are sexy anyway, I honestly do,' she continues. 'If everyone looked perfect with a perfect face and perfect boobs, it wouldn't be sexy as it's not real life.'
