Kyle Richards & Mauricio Umansky Looked So Glamorous at Paris Hilton's Wedding

After feting their own 25th wedding anniversary earlier this year, Kyle Richards and Mauricio Umansky celebrated another momentous family event: Their niece Paris Hilton's wedding!

The pop-culture icon, who is the daughter of RHOBH newcomer Kathy Hilton, wed Carter Reum on November 11 at a private Los Angeles estate, and Kyle and Mauricio didn't miss a minute of the big event. And naturally, the stylish couple picked out incredible outfits.

For the occasion, Kyle donned a gorgeous, emerald-green gown. The silky style had a plunging neckline and a mermaid hem, and its sleeveless silhouette showed off Kyle's toned arms. The Beverly Hills mama paired her gown with a golden cuff and a jeweled necklace and earrings, and she carried a boxy, glittering clutch.

Mauricio looked dapper by Kyle's side. The real-estate mogul wore a black suit, and his jacket was left open to expose a statement shirt. The white button-up was embroidered with black roses, and Mauricio also sported a spiffy pair of glasses.
