Prove to be true friends. Showing up when you have a newborn at home proves that your friendship is the next level.

Haley Bieber showed off exactly that kind of next-level friendship commitment when she turned out to support Gigi Hadid at the Guest-in-Residence store that opened on Saturday night in Los Angeles - wearing adorable coordinated looks. It's a great way to get the most out of your life.

The event appeared at Bieber's first official public event since Bieber gave birth (she and her husband, Justin Bieber, welcomed their son, Jack Bruce, on May 8).

The new mom and model wore a matching burgundy skirt and jacket set, decorated with a small bag and black stiletto pumps on the occasion this week, Bieber took the classic holiday party look and made it herself.Following a true master class on how to wear a red sweater mini dress, she put on a carousel of photos shared on Friday on her instagram account.

Hadid wore multiple guest-in-residence pieces for the storefront, combining the guest-in-Residence stripe rugby with chestnut and true red stripes, and the guest-in-Residence cable vest with chestnut brown cashmere.

In addition to works from her own brand, Hadid wore Calzedonia Invisible20Denier Sheer Tights and Christian Louboutin Donna Penny Loafers, and accessorized the look with a Loro Piana Pocket L19 clutch according to Star Style.

Hadid told Women's Wear Daily that, like the brand's Bond Street location in New York City, the LA Guest in Residence store was the same as when guests visited the model at her home.

"Really, it feels the same," she explained. "We want people to walk into our store and feel like they're in the house of creative friends."" We want people to feel comfortable: sit down, play a game of chess, look around the art and there is ease of use to it.”
