Tracy Sullivan, of Laurel Springs, New Jersey, turned one bedroom of her house into a closet. She admits she has a bit of clothes-shopping obsession. 

Sullivan says, "i'm always going to buy clothes. I love fashion. I love new things. I love what's happening that season." 

Last April, she joined Poshmark , a website she says lets her shop guilt-free. 

"I've bought and sold so many things, and traded, it's just been a rewarding experience," she explains. 

Poshmark members create "closets," listing items they want to sell. Then they can shop the closets of other members, who wear the same size or like the same styles. 

"These are women who want to de-clutter their closets," Sullivan says. "They want to make room for new stuff. They're trying to push things out really qucikly, so, usually, you get a really good deal." 

Poshmark takes 20% of the purchase price, which is less than the cut taken by most consignment stores. 

Once a sale's arranged, the seller prints out a shipping label and sends the item to the buyer , who pays a flat shipping rate. 

Tracy's bought and even traded for shoes, accessories and clothing. 

And she has a whole closet, in her closet, of items she's planning to sell, like a dress she wore to a friend's wedding.Beautiful Fit&Flare Wedding Dressesbari jay bridesmaid dresses 

"I wore it and I loved it, but I'm not going to wear it again," Sullivan says. "I paid about $250 for this dress. I think it's listed for $150 maybe."

In November 2010, soon-to-be Duchess of Cambridge Kate Middleton strolled into the Throne Room in St.cheap mother of the bride dresses James Palace on the arm of fiancé Prince William and stole the hearts of fashion-watchers everywhere. Her sapphire blue Issa wrap dress was perfect for the occasion: sleek and slenderizing, yet demure and oh-so-royal.affordable one shoulder wedding dresses Not to mention that it complemented what adorned her freshly manicured fingers: the 18-caret sapphire and diamond engagement ring that was previously worn by William’s mother, Princess Diana. 

The Issa dress — designed by Brazilian Daniella Helayel — was an instant sensation, selling out in London’s Harvey Nichols within hours. The second shipment of the $535 dress, which arrived on NET-A-PORTER in early December, was gone just as fast. Then the knockoffs took over, some hitting the market for as low as $25.
