Tunic: Boohoo
Trousers: c/o Boohoo via Fashionchick

This tunic is one of the best things I've bought in a while; only about £15, it completely updates a pair of trousers or culottes and adds a dramatic element to any outfit. I wore this for a night out in York a couple of weeks ago and it went down a treat, with my friends totally shocked that both pieces were from Boohoo - plus, it makes a nice change from a dress or leather-pants-and-top combo.
