Lily and Ruby Aldridge Team Up for Gap x Dôen Launch — and Take a Sister Style Quiz! (Exclusive)

The model sisters model the new collaboration — and their looks are so cute you'll be reaching for your credit cards

Lily Aldridge and Ruby Aldridge are teaming up to bring you an effortlessly chic, model-approved spring wardrobe.

The sisters are serving as the faces of a limited-edition collaboration between Gap and California clothing label Dôen, which, according to a press release, "merges Gap and Dôen’s most-loved essentials and California classics in a celebration of individuality and timeless femininity."

The 51-piece collection includes matching sets, dresses, denim, matching tops and skirts, loungewear, and accessories featuring floral prints, eyelet, and flowy silhouettes.

California natives themselves, Lily and Ruby were excited to get behind a collaboration that celebrates breezy-yet-chic style. Plus, Dôen was founded by Santa Barbara-born sisters Margaret and Katherine Kleveland, so the partnership is that much closer to their hearts.

"We love that they're sisters," Lily tells PEOPLE. "I'm a huge fan of Dôen and the Gap. I've been wearing Dôen for years. I've been wearing Gap since I was an infant, so it was such an exciting opportunity, an amazing team, and we couldn't say no."

When it comes to their favorite pieces in the collection, Ruby says she gravitates towards timeless basics.

"My go-to's are definitely more like the camisoles, and the tanks, and the cardigans, and the more sheer pieces," she says. "I love them. I would wear it just with jeans... I want to have this big crazy style, but honestly, I just like wearing jeans and T-shirts."

For Lily, dresses are a staple for spring and summer. "I just live in Dôen in the summertime," she says. "Just really easy cotton dresses, which will just fit seamlessly with everything I already have."

Retailing from $19.95 to $158, the Dôen x Gap collection also has shared styles and prints in kid, toddler and baby sizing — perfect for a mommy-and-me matching moment.

Lily says her 11-year-old daughter, Dixie, has already started dipping into her wardrobe.

"She is a fashionista and she loves fashion and expressing herself through fashion just like I do and just like Ruby does," she says. "It's such a fun expression of self so I'm excited that she gets to wear it too."
