If you've spent countless weekends at a Hamptons estate, wishing you could snap your fingers and have a new designer bag or dress appear automatically, well, you're in luck. While it'll still involve your credit card, Net-A-Porter is ensuring Hamptonites will never have another fashion emergency with the announcement that starting today, they'll offer same-day delivery to nine beachy hamlets, including Sagaponack, Montauk, and Sag Harbor. The magic comes courtesy of StndAIR (the seaplane used by tony hotel The Standard) and costs $25, with orders needing to be placed by 10 a.m. to get in your hands later that afternoon. At the same price as regular express delivery, it's starting to feel practically practical.

Because it's not a rare thing for us to arrive on a beach vacation and immediately wish we'd brought a different bikini, this Lisa Marie Fernandez suit ($300) is bold but a guaranteed good fit thanks to its neoprene construction.

Whether you forgot to pack your party shoes or are simply bored by the pair you brought, Net-A-Porter's new service makes a switch easy. We love Christian Louboutin's bright platforms ($1,095) for a Summer shindig.

Need a beach bag refresher mid-weekend? We'd click through and purchase this buttery soft Bottega Veneta tote ($4,050) for fashionable schlepping of our sunscreen, magazine stash, and more.
