It's been one heck of a social season out East, but summer's not over yet. There are still dinners, fundraisers, and concerts at The Surf Lodge to be had, but by now, we imagine, you've probably exhausted your wardrobe. The only thing worse than getting snapped in the same outfit twice, however, is dropping major dough on a designer dress you'll keep in the back of your closet. What's a girl about town to do?

Luckily, our friends over at Armarium have popped up in The Hamptons, offering the chicest luxury looks on loan. Better yet, London-based designer retailer Browns have just made their US debut on-site. From now until Labor Day, you can borrow (or buy) their coveted new collection at the Armarium Southampton pop-up. They've the perfect look for every end-of-summer event you're sure to attend. And, since you're so busy RSVPing, we've tapped the ARMI to curate the ideal ensemble for each occasion.

Armarium Southampton, 28C Jobs Lane
