If there was ever a time to party, it’s today: Beyoncé day. Here are the best outfits of the week as seen at parties by Chanel, Louis Vuitton, and Saks — plus Netflix’s They/Them premiere and Hulu’s Not Okay.

Most On-Theme: Sydney Chandler

Sydney Chandler attended Chanel’s dinner to celebrate a new boutique in East Hampton wearing this gorgeous Chanel jacket and Chanel choker, which I need ASAP.

Best Pop of Color: Sophia Roe

Sophia Roe knows how to spice up her look with a pop of yellow. While attending the Louis Vuitton cocktail party in Sag Harbor, the chef wore this black leather dress with white heels.

I love everything that’s going on with Gugu Mbatha-Raw and Reese Witherspoon’s dresses at the Surface premiere. Mbatha-Raw’s green gown has beautiful ruffled detailing, while Witherspoon’s short cream dress has fun embellishments.

Hostesses With the Mostesses: Whitney Tingle and Danielle DuBoise

Sakara Life co-founders Whitney Tingle and Danielle DuBoise were in sync at the brand’s Hamptons dinner. Their coordinated-yet-varied looks — a statement blazer over a bra top — make them the trendiest hosts out east.

Best Coordination: Brooke Shields

Brooke Shields had a yellow moment at the Gianvito Rossi and Mytheresa dinner in the Hamptons. This long shirtdress looks luxurious and matches her clutch. It’s called commitment.

“It” Girl of the Week: Zoey Deutch

Zoey Deutch smoldered at the Saks Aspen welcome party dressed in all-white. Her long gown looks effortless and cool, especially paired with the Bottega Veneta bag.

Best Structure: Tiff Benson

“Perfumista” Tiff Benson wore this coral dress to the Scarpetta Beach Diptyque “Paris Celebration of Summer” in Montauk. Between the color and the cut of this dress, she was perfectly dressed for the locals.

Boldest Look: Dylan O’Brien

Dylan O’Brien opted to go big at the premiere of his movie Not Okay, wearing a bright-pink suit with a black tank top and black-and-white loafers to match.

Best Pattern: Alexa Jay

Model Alexa Jay looked stunning in her form-fitting tie-dye dress at the Poppi #BFE (big flavor energy) “poppi hour.” Her black headband and boots elevate the look.

Just Yes: Austin Crute

Austin Crute’s outfit at the They/Them premiere is so simple yet so right. From his polished nails to his jewelry to his pleated pants, the actor looked flawless.

Best Accessories: Caroline Vazzana

Editor Caroline Vazzana knew just how to style her gray matching set, from the chunky rings to the statement earrings to the yellow mini bag. Whoever said “take one accessory off before you leave the house” would have been wrong in this case.
