Refashioner - Editing your wardrobe each season is a liberating, yet agonizing task. But, thanks to a number of online consignment stores and thrift shops, tossing those high school duds in favor of another girl’s relinquished vintage gem couldn’t be more fun (and simpler.) Fashion isn’t all name brands all the time. Refashioner is a great place for the indie-inclined gal to discover unconventional designers and ultra-unique pieces, like calfskin short-shorts and a Vivienne Tam blazer checkered with a Warhol-inspired portrait of Chairman Mao.

Material Wrld - This website provides a trade-in service that promises to be more convenient than eBay, more valuable than thrift stores and faster than any consignment shop. Ideal for those looking to swap unwanted goods for something new in a simple way, Material Wrld mails users pre-paid shopping bags to return their used apparel, and within two to 10 business days, the user then receives gift cards to Saks and Shopbop valued at two to three-times what thrift stores typically pay for the used goods. It's pretty awesome. (Photo: Courtesy of Material Wrld)

SnobSwap - Sometimes we don’t get as much money back as we’d like after a long Saturday spent selling our used clothing....that’s where the buy-sell-or-swap website SnobSwap comes in. This shopping site allow users to trade one stylish item for another and the “Shop by Price” filter also helps to keep you within your budget. Love that. (Photo: Courtesy of SNOBBSWAP)

Bib & Tuck - If you’re very big into brands, then definitely check out Bib & Tuck. The relatively choosy website only accepts particular items from a lengthy list of brands, including places like 10 Crosby Derek Lam and Nike, while excluding others, like Madden Girl and Miss Sixty.

ShopHers - Imagine Net-a-Porter, but the consignment shop edition. That’s a spot-on description of ShopHers, a very high-end designer website where users can buy and sell super swanky stuff, like Academy Award gowns and Hermes Evelyn bags.

eBay - No list of online reselling marketplaces is complete without the most famous of them all, eBay. If you’re looking for a feisty bidding war when you sell that coveted dress from H&M's designer collaboration — look no further. Buyers have also been known to snag some pretty unbelievable finds on the ubiquitous website. (Photo: Courtesy of ebay)
