I saw a very similar jacket at H&M last weekend. Scarf can be found at American Apparel. Jean @Madewell1937. Now shoes, is kind of a problem. Probably yoox.com has something close to these.
I know this look is more of a autumn look, but that's my problem. I'm not really into summer looks. Autumn/winter/spring on the other hand is my thing.
