I am a big fan of denim - dresses, shirts, jeans and jackets.  One of my most useful denim items is my GAP denim shirt.  

At the moment i am wearing it buttoned to the top, while i was pregnant in the summer i wore it open over dresses, its good with skirts, under dungarees, under jumpers, with jeans, you can wear big necklaces over it or long thin chains, its doesn't get to hot when you are pram pushing up massive hills, you don't have to iron it, it looks cool - its a wonder i wear anything else!

Here are some good ones:
