Forget red, Hailey Bieber just declared that brown is the color of the season. This fall, the model has brewed up all kinds of sartorial perfection with a parade of latte-inspired looks — and yesterday, she introduced the brown-on-brown-on-brown trend to one of her all-time favorite outfit formulas. 

On Friday, Bieber stepped out solo for Kim Kardashian's 43rd birthday party at Funke restaurant in Beverly Hills, wearing a brown leather micro miniskirt that showed off her bare legs and a coordinating coffee-colored blazer in oversized proportions. A white T-shirt underneath her jacket provided a frothy finishing touch. She accessorized with her new go-to "B" diamond-encrusted necklace, chunky gold earrings, slingback kitten heels, and a deep red handbag slung over her shoulder. 

Hailey's shoulder-length "cinnamon cookie butter" hair was styled straight and tucked behind her ears with a middle part, while her makeup palette included varying shades of bronze and chocolate. 

Back in September, Hailey first introduced latte (or espresso martini, as she sometimes puts it) dressing to the public during Paris Fashion Week. Redefining the LBD, Bieber wore a brown Saint Laurent dress with long sleeves and micro hemline to celebrate the launch of Rhode's new tinted peptide lip treatments. She styled the dress with sheer stockings and tan leather slingback heels, as well as an espresso glossy lip and a slicked-back ponytail.
