14-year-old Baldwin was totally *that* girl. With choppy layers and honey-blond highlights, the budding model’s hair was peak Y2K. From her glossy lips to her thinly-tweezed brows and bohemian feather earrings, Baldwin’s girl next door aesthetic was #goals for teens the world over.

By the time she was 16, Baldwin had leveled up her beauty routine. The young model traded her thin brows for a fuller look and also began experimenting with bolder lip colors like this rosy coral shade.

Taken the same month that Justin Bieber posted his first picture with his future wife on Instagram, Baldwin stunned in a sleek top knot and bold, graphic eyeliner. The elegant updo, dark eye makeup, and pale lip combo marked a departure from the subtle looks of her earlier years.

At the 2015 Met Gala, then 18-year-old Baldwin debuted her first major hair transformation. Swapping her wheat-blond locks for a rich chocolate shade, Baldwin established that she could pull off both dark and light hair hues.

You can never go wrong with dark lipstick as Baldwin proved at the 2015 Annual Night of Generosity Gala in Beverly Hills. Baldwin’s dark brows and vampy lipstick made her look sultry and striking.

Baldwin was the ultimate California girl at the 2016 MTV Video Music Awards. The then 19-year-old’s choppy lob, matte brown eyeshadow, and light pink lipstick exuded effortless glam.

Baldwin’s Carpool Karaoke episode was full of surprises as was her beauty look for the Carpool Karaoke: The Series premiere. Typically known for tousled, layered beach waves, the model’s platinum flat-ironed blunt lob was very unexpected.

Later that year, Baldwin switched up her hair yet again. Serving Old Hollywood glamour at the 2017 #REVOLVEawards, the model’s shoulder-length curly haircut and bright red lips marked a shift into more dramatic looks.

Petition for Baldwin to bring back her pink hair! While attending the 2018 Met Gala alongside rumored boyfriend Shawn Mendes, the model flaunted a pastel pink bob, flower crown, and rosy, metallic makeup.

Bieber’s 2019 Met Gala aesthetic was a world away from her pink-haired boho look. Her polished high ponytail and oversized hair bow had vintage energy, while her bold cat eye and dewy skin gave the look a modern edge.

Bieber hopped on the bronde hair train, popularized by celebs like Kim Kardashian and Gigi Hadid, in October 2021. The then 24-year-old’s in-between hue proved extra flattering and ushered in an era of darker hair colors.

It’s no secret that Bieber loves a bob. For the 2020 Vanity Fair Oscar Party, the then 23-year-old put a contemporary spin on this tried-and-true hairstyle. An ode to the wet hair look, Bieber’s slick, smooth bob looked ultra-cool paired with a pronounced side part.

It’s the look that launched a thousand manicures. Bieber attended the 2022 Met Gala with her signature neutral makeup and the glazed doughnut nails that would take over the world come summer.

It makes sense that Bieber, a long-time lover of matte brown and earth tones, would gravitate towards this super-rich shade of espresso brown. The dark hair color, which Bieber debuted in October, was sultry to the max.

The skin care mogul proved the mob wife aesthetic is alive and well at Super Bowl alongside husband Justin Bieber, whom many thought would perform with Usher at the halftime show (spoiler alert: he did NOT).

Hailey rocked a leopard-print fur coat with thick shoulder pads by Saint Laurent. Her beat totally matched the vibe, with a smokey eye, heavily lined lips, and darker tresses that would make Meadow Soprano proud.
