Kristen Wiig can't walk in heels.

The 'Bridesmaids' actress says her style is all about comfort and would never wear shoes that hurt her feet for the sake of looking good.

She joked: ''I don't really think about style. As I get older, comfort is more important.

''I so badly want to be that girl who shops with her girlfriends and wears heels, but I can't do it. After one block I'd have to go buy flats.''

The 39-year-old star tries to keep fit and look after her skin, and credits her healthy lifestyle with her youthful appearance.

Kristen revealed: ''I take care of my skin and I try to exercise a little bit here and there, but not as much as I should. I walk and I do yoga sometimes. I eat well and I meditate - I think it's all connected.''

The brunette also spilled the beans on her go-to designers, citing celebrity-favourite Victoria Beckham as one of her wardrobe staples.

Kristen said: ''I love Alexander Wang, The Row, opening ceremony and Victoria Beckham - her dresses are amazing!''

And she explained why she changes her hairstyle so much, claiming she gets bored with the cut and colour of her tresses after a few months.

The star said in an interview with Britain's LOOK magazine: ''My natural colour is dark brown. I get bored easily so I'm constantly changing it - it's fun. Also, I like my hair to look a bit different in each film that I do.

''Right now, I'm trying to grow it out. It keeps getting this long and then I keep cutting it.''
