Two vintage boutiques are joining forces for a huge vintage sale beginning tomorrow, and we scored a sneak peek just for you. Frock, the Orchard Street staple vintage boutique curated by Alexandra "Lexi" Sacchi and Evan Ross, will join with the Garment Room, a Chicago favorite, for a three-day pop-up store on Prince Street in the old Phat Farm space. This marks the second time the two stores have collaborated, hell-bent on the notion of stocking only the most wearable, functional selection of vintage clothing and accessories. What does that mean for us shoppers? Vintage bags from Gucci, Carlos Falchi, and Pierre Cardin for $85 to $400 (with the exception of Chanel or Hermès , of course, priced up to $1,000 because "these are the bags women fight hands-over-fist for," Lexi says). Plus, plenty of day dresses and separates from Lanvin, Yves Saint Laurent, Ossie Clark, Bill Blass, Thierry Mugler, and more. The sale starts tomorrow and lasts until Sunday. But why wait? Check out a sneak preview after the jump. It might be worth your while to brave the rain.

V Is for Vintage Sale, 129 Prince St., nr. Wooster St.; through 9/28, Fri.–Sun. (11–8).
