If you didn't respond "YEP!" when someone said "white tee," then you weren't doing it right. The white tee is one of the most controversial trends ever due to it's symbolic reference to drug-dealing on the corner, but that crisp white joint was one of the cleanest-feeling and looking pieces in your rotation.
Like the intro to the video for Dem Franchize Boyz' "White Tee" video says, "Great news! I just saved a ton of money on my wardrobe by switching to white tees." Who would have believed that such a simple item would became so iconic.
