Last night, Daniella Kallmeyer kicked off the summer party season with an unforgettable birthday soirée. The visually stunning design studio, Apparatus, was transformed into Cafe Kallmeyer for the night with fashion insiders, actresses, and models putting their summer party looks to the test.
Of course, Kallmeyer made jaws drop in a sculptural wrap paired with coordinating trousers. To help her toast the evening, Severance actress Britt Lower, And Just Like That star Sarita Choudhury, and “Alaska” singer Maggie Rogers were among the chic revelers in the building. All in all, the festivities served as a chic lesson in what to wear to a friend’s birthday party. Whether you’re getting together for a rooftop gathering or a dance rager, take notes from last night’s cool attendees.
The Elevated Graphic Tee & Statement Pants

Ok, maybe not all of us have friends who are major fashion designers, but you can still show your support with playful merch that honors the birthday girl. Here, Lower reps the honoree with a Kall Gal tee. The biggest lesson here is all about balance. If you’re going super casual on the top with a tee, elevate the look with a fancy pair of pants like these Fall 2026 Kallmeyer embroidered beauties.
High-Texture Neutrals & Asymmetric Silhouettes

You never want to outshine your friend, but you can still make a subtle statement. The classiest way to do so is with lush texture and asymmetric silhouettes à la Choudhury. Bonus points if your shoes are easy to kick off for when the party really turns up on the dance floor.
Sharp, Deconstructed Tailoring

Exacting tailoring will always be your friend for sharp day-to-night dressing. Follow Louisa Jacobson’s lead and wear a white-on-white tie and button-down shirt. Let timeless trousers add the finishing touches to the polished party look.
Sheer Tops & Subversive Basics

Breezy sheer tops feel special enough for the moment without overdoing it. Maggie Rogers demonstrates how to execute the party-ready look with black separates and a long pearl necklace.
Tactile Knits & Pop-of-Color Utility

Playful pops of color like red and mustard will rise to the occasion. Keep the cool-girl vibes going by pairing tops with utilitarian cargo pants and colorblocking bags.
The “Borrow-from-the-Boys” Cool-Girl Uniform and The Ruched Maxi

A menswear-inspired look always takes the cake, but if you’re in the mood for something on the other side of the sartorial spectrum, turn to a trusty maxi dress to celebrate the evening in.
