A new boutique filled with such discounted designer gems: priceless.

Well, almost.

Cary Lane is Noe Valley’s newest must-know address. Run by two gents with serious insider connections, the cheery shop with light blue walls brims with goods from local indies and famous designers at impressively reduced prices.

You’ll score Erin Mahoney gowns, Addict bombers, Hudson jeans, tops by Quail and Twelfth St. by Cynthia Vincent, Shoshanna bikinis, and Nobis knit hats. The men’s stock also rocks.

Sign up online to get the scoop on sales and new merch (which rotates frequently).

So you can master this domain.

Cary Lane, 3813 24th Street, at Church Street (415-896-4210 or carylanesf.com).
