One of my favorite designer consignment shops online is Portero .com. The company describes themselves as the leading curated source for ‘premium, pre-owned, prized’ authenticated luxury goods. They were founded in 2004 and carry all the major luxury brands including Chanel, Hermès and Rolex. You can find just about anything your want and need including the finest handbags, watches, jewelry and accessories.
Designer Purse Outlets .com is always a reliable source for discount and promotions that you won’t find at many other online designer consignment shops. The company uses a reputable third party auditing agent to ensure the authenticity of their items; however, remember to always double check yourself when you receive your item just to be sure. I found the site easy to navigate with all the various brand names listed alphabetically in the left pane column.

Jill’s Consignment .com was founded by Jill Sadowsky who describes herself as a passionate fashionista. She has quite a history in the industry as her great grandfather, Ruben Sadowsky, was the largets cloak manufacturer in New York in the 1900s. In 1996, Jill opened the Florida Consignment Store and then gradually evolved online. Their inventory changes from hundreds of items to perhaps just a handful depending on supply and demand. One of the best designer consignment shops online, Jill’s Consignment can be your one stop source to satisfy all your fashion needs and desires.
