14 photos show how Sofia Richie evolved into the ultimate quiet luxury icon

In the early 2010s, Richie Grainge was best known as the daughter of singer Lionel Richie and the younger sister of Nicole Richie.

Family ties to the entertainment industry meant she grew up attending red-carpet events. One of her earliest red-carpet appearances was at Justin Bieber's "Believe" concert movie premiere. For the event, Richie adopted a grungy aesthetic.

She wore chunky biker boots, leather pants, and a graphic T-shirt under a black mid-length coat. She accessorized with a large emerald clutch.

Three years later, Richie Grainge was still very much in her grunge era.

Attending a New York Fashion Week event hosted by Refinery29, she wore a sheer T-shirt layered over a red lace bra, ripped skinny jeans, and a pair of platform boots with colorful detailing around the ankles.

Richie Grainge made her runway debut at NYFW that year. She told E! News at the time that she "never thought I'd actually be in this position of ever walking the show, and here I am."

Richie Grainge was clearly a fan of loud luxury in 2016.

She was spotted heading to a nail appointment in Los Angeles with her puppy, Flynn, wearing a logo-heavy ensemble consisting of an oversized Moschino T-shirt, black leggings, and sock-style sneakers.

Richie Grainge was one of many "it girls" who rocked the "bra as a top" trend at the California festival in 2017, Vogue reported. She paired the white top with baggy red pants, an unzipped Vetements x Reebok jacket, Vans sneakers, and pink-tinted sunglasses.

She added a touch of loud luxury to her street-style aesthetic with a Louis Vuitton belt bag.

Richie Grainge still favored a grungier aesthetic in 2017. She wore a custom-made Topshop gown with a gold sheen and a daring low-cut neckline for her third appearance at the annual Met Gala in New York.

She accessorized with a leather biker jacket, a black handbag with metal detailing, and an assortment of silver Chrome Hearts jewelry.

Her final accessory was a matching friendship tattoo she got with her stylist before walking the red carpet.

Speaking to Teen Vogue ahead of the event, she said that the most important thing in her approach to fashion is that she feels "confident in the outfit."

It's "the only thing that matters," she said.

Richie Grainge wore a strapless pink satin dress with a snake-shaped silver Bulgari necklace. She also wore a silver bracelet, rings, and earrings by the luxury Italian fashion house.

She kept her hair swept up into a bun with a side part, reminiscent of the signature slicked-back look she often sports nowadays.

The timeless ensemble is one of the first that Richie Grainge wore in public that leaned into the quiet luxury trend. Unsurprisingly, it drew comparisons to Marilyn Monroe.

Richie Grainge's 21st birthday outfit was anything but minimalistic.

For the big milestone, she celebrated with friends and her boyfriend at the time, Scott Disick, at the Wynn Hotel in Las Vegas. She told Elle following the celebrations that she and her stylist knew they wanted to "go big."

"I have a few outfit changes throughout the day," she said. "Each outfit is fun and sexy."

Her boldest look, however, was the glitzy pink Yousef Aljasmi jumpsuit she wore to the nightclub portion of her birthday. She paired the bold ensemble with clear heels and wore her hair slicked back with a braided extension.

The silver embellished two-piece set from La Bourjoisie consisted of a high-waisted skirt with a daring thigh-high slit and a semi-sheer long-sleeved top.

Richie Grainge paired the look with chunky gold earrings and nude stilettos, wearing her hair in a slicked-back ponytail.

In 2020, Richie Grainge partnered with the Australian denim brand Rolla's to launch a limited capsule collection. She aptly wore jeans for the launch that she cinched at the ankles with silver cuffs.

She paired the denim with a black blazer under a chunky corset belt.

She was spotted in May 2021 arriving at Craig's, a celebrity-favorite restaurant, wearing a simple white crop top, wide leather pants, and a black wool coat from The Row.

The Row, a fashion label founded by Mary-Kate and Ashley Olsen in 2006, is considered one of the hottest quiet luxury brands. By wearing one of their coats, Richie Grainge indicated she was gravitating toward a more understated, chic aesthetic.

Richie Grainge and Grainge, who started dating in early 2021, made a joint appearance at the Elton John AIDS Foundation Academy Awards viewing party. The couple coordinated in classic eveningwear — Richie Grainge wore a simple black Tom Ford gown, while Grainge sported a traditional black tux with a tie.

Richie Grainge added a pop of color with a leopard-print clutch and wore her hair in her signature bun.

By 2022, Richie Grainge's days of rocking logo-heavy graphic T-shirts and pants on her days off were well and truly over.

Instead, her casual attire leaned heavily into the quiet luxury aesthetic she's now known for.

A prime example was the chic outfit she was spotted wearing in NYC in September 2022. It consisted of a loose white shirt tucked into straight-ankle jeans, cinched with a silver belt at the waist. Richie Grainge added a touch of luxury with black-tipped Chanel flats and a blue mini handbag.

For one of their last public appearances before announcing their pregnancy, Richie Grainge and Grainge arrived wearing another set of chic coordinating looks.

Grainge wore a classic black suit paired with a white collared shirt, and Richie Grainge also opted for an all-black ensemble.

Her ribbed Chanel dress was adorned with feathers and was sheer along the lower section. Keeping to her usual hairstyle, Richie Grainge wore a slicked-back bun and several silver jewelry pieces.

Days after her pregnancy announcement on January 25, Richie Grainge stepped out in LA in a casual yet elevated look. She wore green R13 denim overalls layered over a cream cashmere sweater rolled up to her elbows.

The mom-to-be wore her hair down in loose curls, accessorizing with thin oval sunglasses, white derby shoes, and a black-and-white Ferragamo Hug handbag.
