I bought one of these 2 years ago from Topshop and stopped wearing it as I didn't really know what to wear it with. However, I am now really coveting one from Warehouse:
I adore the cut on this - past the hips, zip slightly off center but still has a slim-fit feel to it. If you want to pull of a style like this, this item is definitely the way forward. Wear with a loose fitting white dress/playsuit and a pair of stilettos for a chic office summer look, or with leather look black trousers (also loving Warehouse one's) for a day time feel!
At £70, it's a bit pricey, but manageable and think of the styling oppurtunities!
