Liam Payne has the most expensive fashion taste in One Direction.

The band's stylist Caroline Watson, 33, has revealed the 19-year-old singer is harder to please than his bandmates - Niall Horan, Zayn Malik, Harry Styles and Louis Tomlinson - because he has such expensive tastes.

Speaking to LOOK magazine, she revealed: ''Liam's got the most expensive taste. He'll say, 'Oh, I've seen this Dior jacket I like, and I think, 'Uh oh.'''

The celebrity style guru - who has also worked with stars including Britney Spears and JLS in the past - also revealed Harry, 18, is a big fan of her work, but that leads to problems as he often takes clothes home with him without asking.

She said: ''Harry's terrible for taking clothes. We'll do a shoot and some jeans will be missing, then I'll see a picture of them on a night out.''

Caroline also praised the way Zayn's style has changed over the last year.

She explained: ''In the past year his style has evolved. Before he was all about baseball jackets and trainers, but now he's really into vintage pieces.''
