Sofia and Nicole Richie Have a Sister Style Moment in Glamorous Gowns at the Baby2Baby Gala

Sofia Richie Grainge and Nicole Richie are stylish sisters!

The duo posed for photos together at the Baby2Baby Gala presented by Paul Mitchell on Nov. 9 in Los Angeles, both wearing glamorous gowns for the event.

Sofia wore a black Alessandra Rich gown that featured creamy-white straps and a bow detail. She teamed the sleek dress with a black purse and black, sling-back heels and wore her hair tied back in a stylish up-do. Sofia stuck with nude tones for her glam, and wore a pair of chunky white hoop earrings, as well as several smaller hoops.

Nicole, meanwhile, opted for a full length purple Lanvin gown with textured detailing, long sleeves and a turtle neck. She wore her hair loose and complemented the color of her dress with purple-pink eyeshadow and a nude lip. Gold drop earring and several rings completed the chic look.

Both sisters are known for their chic styles on and off the red carpet.

Sofia, 26, who welcomed her daughter Eloise with her husband, Elliot Grainge, 31, in May, stepped out with him for their first night out since becoming parents in October.

The new parents posed on the red carpet together at the Academy Museum Gala in Los Angeles on Oct. 19. 

Sofia wore a sophisticated high-neck orange-red silk dress from Fendi’s spring/summer 2024 collection. The dress had soft side draping and grazed the red carpet.

She complemented the glamorous look with Tiffany & Co. jewels and a black handbag. Her glam featured a slicked-back hairstyle and an elevated natural makeup look.

Her husband wore a black suit with a white button-up shirt and black tie. His glasses featured lenses that nearly matched the color of Sofia’s gown, tying their looks together.

The new mother recently told British Vogue that motherhood won’t change her style, which consists of polished yet simple looks paired with her typical slicked-back bun. 

“No, I’m not altering my style because I’m a mom. I’m super confident and comfortable in the way that I dress,” she told the publication. “If anything, my bag is just a lot fuller.”

On the other hand, Nicole, 43, has been known for her fashion since the early 2000s. 

She reunited with her Simple Life costar and real-life friend Paris Hilton at the CFDA Fashion Awards in October. 

The fashion designer wore a long backless leather black dress with a boat neckline. She wore black heels and accessorized with drop earrings. Her makeup look featured a pink eyeshadow, and she pulled her hair into a slicked-back bun.

Her partner-in-crime, Hilton, wore an Oscar de la Renta minidress featuring vibrant red flowers, which she paired with shiny red heels. 

PEOPLE exclusively announced the Dec. 12 premiere of Paris & Nicole: The Encore on Peacock — a new project 21 years after The Simple Life.
