The problem with the periodic searches for baggy skateboarder clothing and true hip-hop fashions for Poser is that basically, they don't exist. BillyT's outfit is an exception, but that's only one style for only one figure. There are lots of "almosts" around, though, and with some creative mixing and matching, and perhaps some magnet and re-scaling work, you can probably come up with something good enough. Xena's Everyday Wear for Hiro at PoserPros is often cited as a good start because of the hoodie that comes with the set.
