If you haven't heard of Threadless, you need to. It's a site for independent designers to publish their work and have users rate and buy them. To be honest, I feel like a lot of the clothes on it are kind of lame. Most of them remind me of the type of clothes you'd see the odd emo kid in the back of the classroom rocking. In fact the only one's I'd consider buying would be the ones shown above.
But that dosen't mean I don't see potential. If people could start releasing some streetwear on there, I'd be ecstatic. Exclusive streetwear+ affordable price= me happy. So if you want to get your clothes out there, get to work.
