Nicole Richie looked gorgeous Thursday night while arriving to the 10-year anniversary celebration for clothing brand Ella Moss held at Eveleigh in West Hollywood. A decade in the biz ... congrats!

Wearing a flowy dress, her hair in a braid and black heels, Joel Madden's wifey looked picture perfect. Love the black nails, too!

Joining Ms. Richie at the fashion line's celebration ... Twilight star Ashley Greene. Nothing like a hot Hollywood hotspot, gorgeous clothes and two stunning starlets.
