What I Want to Wear

So I don't usually post anything like this, but this was too good not too. I stumbled across this picture on Look de Pernille about a week ago, and it's been on mind ever since. This is 100% what I want to be wearing this summer (minus the cigarette), but maybe with converse instead. 
If anyone can point me in the direction of a shirt and skirt like this it would be much appreciated!
