Baby and Co.'s sixth annual Designer Closet Sale is upon us, and owner Jill Donnelly has promised a particularly off-the-hook selection this year.

Here's how it works: Donnelly collects pieces from her best customers' wardrobes—pieces like McQueen blouses, Prada pumps, your favorite Rag and Bone jeans—and organizes this pop-up consignment sale of sorts. Prices are fair to say the least (a certain style editor scored an Alexander Wang jacket for about $80 one year), and 10 percent of the proceeds benefit the Mockingbird Society.

If it's anything like years past (and likely it's bigger and better), here's our advice: bring cash and sport some underthings that allow for public quick changes.

The sale starts this Thursday, August 14 and lasts through Saturday the 17. And, you know, early bird gets the worm and all that.

We'd love to know what you make it home with. Tag @SeattleMet on social media to share your scores.
