If u want to be wearing t-shirts that are actually cool, and have unique designs and an urban feel, then check out Karmaloop! I've bought so much clothing from these brands because I know that not many other people know about the brands yet.
This is his (Sike) website, where he blogs and sells his overhemd, shirt designs under the 'sike shop' link. check it out - his designs are pretty cool. =)
