If you’ve already decided to buy the Pixie Lott designed t-shirt, why not carry on the good deeds and go on a charity tee roll? Designer t-shirts are definitely having their moment right now, as a number of fashion houses have been producing their take on the normally cheap classic. But as these versions usually cost at least £60 (right now, for example, you can get this very cool Marc by Marc tee for £65, while this similarly brilliant See by Chloe number will set you back a mere £105), it’s usually better value to head to your local Urban Outfitters for a cheap and cheerful graphic tee.

The charity-designer collaboration is a classic one, and this time around it’s the Environmental Justice Foundation that’s launching a pop-up boutique in London’s Carnaby Street. Open from today for just two weeks, all t-shirts cost £30, and with designs by Luella (pictured), Giles Deacon and Richard Nicoll, we’d highly recommend getting down there as soon as possible – the tees are on sale only until they sell out!
