Nicole Richie joined in on H&M's celebration for NBC's "Fashion Star" last night (April 24) in New York City.

She rocked a mustard and navy chevron printed dress with long bell sleeves and a fitted silhouette by Winter Kate.

Nicole accompanied her cool yet vintage-inspired dress with statement jewelry by House of Harlow 1960, a clutch by House of Harlow 1960, and bright red Brian Atwood "Maniac" pumps.

A tall bun, dark eye makeup, and a nude lip shade finalized her look.
