Leggings!
I do like leggings, I know most fashionistas like to hate them and they're so 80's but they're so easy to wear and they're just not going to go away. For spring lots of leggings were seen on the catwalk - think Threeasfour, Viktor & Rolf and Alexander McQueen. Lots of bold and graphic prints. American Apparel has a great selection starting at £22 and the Scandinavian label Nümph has some nice bright colours for £25.
