There are tons of Euro-based online shopping sites, but this one kinda makes it hard for its shoppers to make fashion mistakes. 
They give fashion tips, but the funny part is how they put outfits together which are similar to what celebs are wearing. You too can dress like Justin Timberlake, but can you boogie like him? Too bad they don’t have a US based website.
some looks from asos I like:

A chill and basic cardigan and jeans look with a vneck tee and white sneaks has comfy and kick back written all over it .
This vest and slim jeans look is all over the indie scene, but without the fedora and long unwashed hair, it’s much more fresh.
