I love mostly Japanese street fashion brands: Sex Pot Revenge, Super Lovers, Listen Flavor, 6%DOKIDOKI, Putumayo, and many more.
For Western fashion, I really like H&M's DIVIDED line (it has quite a Harajuku influence to it, I think), Tripp/Royal Bones and Killstar. I also enjoy Vivienne Westwood, Chrome Hearts, Betsey Johnson and Bas Kosters, but I will never be able to afford any of it.
I mostly buy stuff from thrift shops, though.
