Colour-blocking is big news, gone are the retro prints from the flighty echelons of the fashion world. This hoodie from Topshop (£20) is a prime example of colour blocking. It looks more effective if you stick to colour blocking with individual items within an outfit, but the lemon yellow looks good against the black and blue. You could go the whole hog and team it with purple jeans and hi-tops, but you don’t want to look like a Skins reject do you?
