There’s been no shortage of clothing lines by rappers over the years, but when you consider the ones that have actually survived the times, well, that’s a completely different story. The likes of Rocawear, Sean John, and (somehow) Phat Farm have been going on for a decade strong, mainly because of the lasting legacies of the personalities behind the brands.

Thus, it was the lines by rappers-of-the-moment trying to cash in that came and went, but even some big names couldn’t make their clothing work when they themselves always looked as if they couldn’t dress themselves. Here’s GIANT’s look back on all the lines that have faded into oblivion.
