Nina Dobrev, Lily Collins, & Elizabeth Olsen Indulge at Jennifer Klein's Annual Party!

Nina Dobrev, Lily Collins, and Elizabeth Olsen make their way out of producer Jennifer Klein‘s annual Day of Indulgence party on Sunday (August 13) at a private residence in Brentwood, Calif.

Also in attendance were The Orville‘s Halston Sage and Elizabeth‘s Ingrid Goes West co-star Aubrey Plaza.

Jennifer hosts the event every year and it draws a star-studded group of celebs, who receive pampering sessions, tastes of the hottest foods, sips of trendy new drinks, and lots of awesome swag.

There were lots of brands on site, including Lizzie‘s older sisters Mary-Kate and Ashley Olsen‘s line Elizabeth and James.

Cosabella had celebs lining up for their undies, Lizzie Scheck had nearly everyone buying her zodiac necklaces, and Quay had celebs leaving the party in their sunglasses. Other brands that participated included Theory, Calypso St. Barth, Kendra Scott, Henri Bendel, and Alexis Bittar.
