Surf, sand, and shopping - isn't that what summers in the Hamptons are all about?

If you're a Montauker in need of some designer retail therapy between rounds at Ditch beach this month, you're in luck: Intermix just launched a luxe new pop-up at Ruschmeyer's!

Taking over the hot spot through July 24th, Intermix is offering an exclusive edit of summer essentials from brands like Isabel Marant, CaraCara, Staud, Agua by Agua Bendita, RE/DONE, and more, all inside one of the hotel's very 'grammable cabins. In addition to browsing the racks, visitors can partake in summer games and daily activations to win fashion and beauty goodies.

To celebrate the Montauk residency, the retailer's Chief Merchant Divya Mathur was joined by Zanna Roberts Rassi to host a VIP preview of the shop followed by a colorful, surf-inspired garden party down the road at Hero Beach Club. 

A slew of stylish guests, including Rocky Barnes, Sai De Silva, Jessica Wang, Kate Bock, Cass DiMicco, and Tayshia Adams stepped out for the beachy bash, where they enjoyed music by Kate Usher & the Sturdy Souls, signature cocktails from Casa Del Sol, and, of course, plenty of fashionable photo ops.
