Last night, L.A.’s cool girls came together for a dinner celebrating D?en’s new capsule collection for Net-a-Porter. The line, designed by Santa Barbara–born and –raised sisters Margaret and Katherine Kleveland (who founded D?en in 2015), marks the brand’s first-ever retail partnership. The siblings seemed to welcome spring with the collection—flowy, bohemian styles, 15 pieces for women and three pieces for girls.

While the Kleveland sisters are certainly their own best models, the dinner’s attendees gave them a run for their money; guests including Busy Philipps, Michelle Monaghan, Odette Annable, and Samantha Traina showed up in their favorite D?en pieces.

During cocktail hour, everyone sipped Champagne on the private upstairs rooftop at Gjelina restaurant and enjoyed a performance by D?en muse and singer Alyssa Miller. Korey Dane, her Primrose Forever Sanctuary bandmate, then joined her, and the duo sang two original songs.

Once the performance wrapped, guests proceeded to a candlelit dinner to enjoy a four-course meal. Dishes included pomodoro burrata pizza, Einkorn orecchiette with duck Bolognese, and a chocolate pistachio tart. Everything from the table runner to the napkins was designed with feminine prints from the new collection. The floral designs came to life in white vases filled with blooming buds and pink ranunculus, while the intimate setting reflected the brand’s pillar of sisterhood and community.

The new collection paid homage to D?en’s California roots with delicate, playful lightweight fabrics, and it was inspired by the dreamlike watercolors of Georgia O’Keeffe and the Abstract Expressionist stain paintings of Helen Frankenthaler. Of the brand, Miller said: “I’ve been in fashion for 15 years, and you don’t come across women who are designing for a real woman. Their clothes are for the home, the office, and the stage. Nothing’s mass-produced, and you’re walking around with a community.”
