Ever get the eerie feeling that all the boutiques in San Francisco have merged into one enormous, Theory-strewn shop?

Finding something unique in the racks of overplayed designers can be a challenge, to say the least.

So head over to Mingle, Union Street’s new shopping destination. Similar to a co-op in concept, it’s a space where emerging fashion designers sell their clothing, accessories, and art — dresses and tops by Erin Mahoney, hand-painted silk dresses by Jeges Designs, lingerie by Porcelynne, knits by Marco Marco, and jewelry by Rena Tom. For men there are deconstructed shirts by Spare Change Designs, jackets and denim by Caffeine, and T-shirts by Mind Trix. With new designers being introduced all the time, you’ll always find something totally original.

Who knows? Your favorite Mingle discovery might become the next Theory.

Though by the time that happens, you certainly won’t see it there anymore.

Mingle, 1815 Union Street, between Octavia and Laguna Streets (415-674-8811 or mingleshop.com).
