Unless you know exactly what you're looking for on eBay, success is nearly impossible; search for "hoodie", and you're liable to get thousands gym-class reject Champions and some dude's plant named Hoody. Cut out the crap, at WallStreetWear.
A currently private-alpha network for buying, selling, and trading urban-ready threads, WSW was named for its capitalization on said trio of Wall Street buzzwords, cause nothing's more street than confusing everyone as to what kind of clothes you're selling. All members're welcome to post new/used threads through one of three plans: a seven day free listing, a $1 two-weeker that includes search optimization features, and a $30/month subscription w/ unlimited 30-day postings; all include easy photo-upload capability, plus sizing and user-determined condition info, though like that Griffey Jr. card you bought off the fat kid, non-mint items could possibly be covered in someone's unique stank. You can purchase gear through PayPal/c-card, and sellers're vetted by other members via a "feedback" percentage; if a seller's willing to entertain trade offers, they can specify what they're seeking in return, and there's also a "Make an Offer" button that lets you propose an exchange, to which the seller can accept, decline, or make a counter-offer, which you'll wait out until they realize just how much they really want those ham sandwiches.
While the still-in-alpha status means the pickings're a bit slim for the moment, they promise to swell soon, and there's currently finds like a Foober hunting-patterned hoodie, a Huf Dirtbag Crew zip-up sweater, and a vintage Bulls Starter jacket -- ironically, something you already found on eBay during your routine searches for elderly livestock.
