Hairstyles are the best way to get a new season look. It's a good deal cheaper than a whole new wardrobe, it takes less time and it's rather satisfying, too.
The length du jour is getting shorter so where we used to see glossy manes cascading down A-list backs, mid-length cuts are taking over, with Jessica Alba joining the gang earlier this year. Bobs are still a favorite, too, making the perfect accessory for a chic outfit. Then there's the celebrities who go one step bolder: the pixie crop. Though Emma Watson has let hers grow out, Amber Valletta and Audrey Tautou are still working theirs.
If short hair isn't your thing, there's the long-haired celebrities who will never chop off their locks, like the red carpet-ready model clan like Cara Delevingne, Miranda Kerr and Rosie Huntington-Whiteley, as well as Suki Waterhouse, Olivia Wilde and the other bed head boho babes. We can't see Olivia Palermo or Jessica Biel getting rid of their trademark sleek styles any time soon, either.
Fancy a change from loose locks? There's fishtail plaits, simple ponytails or high buns, which are easy to do, and make for the perfect 'do, day or night.
Whatever your hair is like - or is going to be after your new haircut - the style options don't stop there. As well as length, you can experiment with colour. Brown or blonde hair are the usual options, but more A-listers are experimenting with ombre dye which enhances pretty much every 'do, whatever your skin tone and colouring. Or, go peach a la Sienna Miller for a gorgeous glow - even in winter.
