If the words pool party bring to mind shrieking spring-breakers or Marco Polo-ing children, we're here to change your mind. In Long Island\u2019s lush Hamptons area, we borrowed a beautiful estate \u2014 notable for its stately architecture, verdant landscaping, and gracious entertaining spaces \u2014 to throw a chic pool party just in time for the start of summer. Making use not only of the sprawling outdoor patio but also the welcoming living areas, including the elegant open-plan living room and inviting kitchen, we set up the ultimate day of relaxation and fun for sophisticated guests with a poolside playful streak. Here, the tricks to steal for your own piscine-adjacent party.The beautiful Hamptons home, situated in Sagaponack in New York, is currently on the market with Sotheby's International Realty.Include Thoughtful TouchesGone are the days of slathering on globs of oil and laying out to catch rays\u2014this is a party for adults, after all. Have umbrellas at the ready for sun-conscious pool partyers and add extra special touches, like a selection of sunscreens and a circular tray for guests to store their sunglasses whilst taking a dip.Set up the outdoor bar in a shady spot\u2014like this pool house countertop\u2014to prolong the lifespan of icy drinks. Champagne, local beer, and refreshing ros\u00e9 create a festive spread, but most important is keeping guests hydrated. Spruce up the water station by filling large spouted drink dispensers with sliced lemon and mint-infused H20 and tart pomegranate iced tea. Don\u2019t forget fun garnishes like extra pomegranate seeds, sliced citrus, and loose mint\u2014the more interactive the drinks station, the more likely guests are to visit it often!Create a Make-Your-Own-Margarita BarAfter they\u2019ve enjoyed the pool, show your guests to the kitchen where they can craft their own margarita; we set up a station at the gracious island, which accommodates thirsty partygoers on all sides. Offer various fresh juices in clear pitchers\u2014think grapefruit, blood orange, lime juice, and pomegranate juice\u2014and cut the accompanying citruses to serve as an edible garnish. Lay out glasses (like these designs that are wrapped in rattan) to be filled with variations of the simple recipe below: INGREDIENTS2 ounces tequila 2 ounces fruit juice of your choice 1 ounce lime juice 1 /2 ounce agave nectar or simple syrup DIRECTIONS Fill a small cocktail shaker with ice and pour in the tequila, fruit juice of your choice, lime juice, and agave nectar. Put on the lid and shake for 30 seconds. Pour into your glass and garnish with fruit.Set Up a Game RoomWhen your guests\u2019 fingers start getting pruney from one too many laps in the pool, take advantage of a room with indoor-outdoor flow to continue the fresh-air fun inside. Decorate with fragrant potted trees and topiaries to bring a verdant atmosphere into your home, turning your living room into an interactive game room. Whether you're spearheading a round of backgammon, chess, or something more lighthearted like charades, be sure to have a basket filled with towels at the ready for guests to sit on, guarding upholstery against wet bathing suits.Take Activities Back Outside A grown-up pool party includes activities for both land and water, so set up lawn games like croquet and bocce and challenge your guests to a tournament in the grassy lawn beside the pool. Utilize Every Area of Your SpaceOnce they've worked up an appetite, encourage guests to take a break and grab a snack in the bright, airy dining room. Serve easy-to-handle bites like watermelon and feta skewers, open-face tartines with brie and crunchy apples, and grab-and-go snacks such as chips and dried fruit on melamine plates that look sophisticated but can also withstand poolside fun. No need to skimp on napkins at this party; skip flimsy disposable paper and opt for chic cotton. We love this indigo style\u2014it may look even better when it gets a little sun-bleached at the edges.Set Up a DIY Gourmet S'more StationAs the sun goes down and temperatures drop, gather your company around an outdoor fireplace or fire pit livened up with a colorful outdoor rug underfoot and h floor pillows for extra seating. Ramp up the ambiance with large outdoor hurricane lanterns stocked with sizable pillar candles for even more glow, and serve a summer-ready take on campfire treats by offering grilled pineapple s\u2019mores with flavored marshmallows and an array of gourmet chocolate.Offer a low-calorie alternative of simple grilled pineapple and peach slices to those already preparing for their next pool party (but rest assured that there\u2019s no way it will compare to the wildly gracious, fun-filled day they\u2019ve just had with you).Prop Styling by Christopher WhiteSee the rest of this Hamptons, New York home on Sotheby's International Realty.
