Kyle Richards' Daughter Sophia Umansky Brought Beverly Hills Elegance to Prom

In case you didn't know from all of those over-the-top promposals that have gone viral over the past few weeks, it's prom season — and the Real Housekids are dressing to the nines for the occasion. Case in point: Kyle Richards' daughter, Sophia Umansky. 

Sophia just had her prom, and she looked elegant as can be as she headed off to the big dance in a beautiful black gown. Of course, Kyle and her husband Mauricio Umansky were there to see their daughter off.

Kyle also posted a sweet pic of Sophia with her prom date, Ben, who seems to have gotten The Real Housewives of Beverly Hills fashionista's seal of approval.

Kyle's four daughters, who, in addition to Sophia, include Farrah Aldjufrie, Alexia Umansky, and Portia Umansky, recently sent a lot of love to their mom and vice versa in honor of Mother's Day.

Sophia, 17, will soon be graduating high school and heading off to college, which is something that Kyle isn't exactly ready for. We mean, don't you remember how emotional Kyle was while sending daughter Alexia off to college in Season 5 of RHOBH? "I have never gotten better so far," Kyle told The Daily Dish in February. "I'm not gonna change. A leopard does not change its spots. So I know I'm gonna be tortured when Sophia leaves."
