Kathy Hilton and Kyle Richards Looked So Chic at Paris Hilton's Bridal Shower

Paris Hilton's enchanting bridal shower had incredible decor, decadent treats, and some seriously up-leveled champagne service. It also had great style, as evidenced by Paris' mother Kathy Hilton and aunt Kyle Richards.

The Real Housewives of Beverly Hills sisters wore floaty, whimsical cocktail dresses to the afternoon event at Kathy's Bel-Air manse. Kyle opted for a long-sleeve black dress with a rainbow-hued neckline and a vibrant floral print. She paired the frock with some bright red-orange shoes and a green Birkin bag, and she carried a teeny white dog as the cutest final touch.

For her part, Kathy chose a pink-and-white look with ruffles and a floral print. The mother-of-the-bride-to-be also wore pink, pointed-toe heels and dangling pink earrings shaped like upside-down flower blossoms. And of course, both sisters had impeccable blowouts and pretty makeup looks that included pale-pink lipstick and fluttering lashes.
