Billie Eilish's Best Beauty Moments

Eilish's red roots seemed to be short-lived. Before winning her second Oscar alongside her brother, Finneas, she debuted her return to long dark locks on the red carpet. 

Upon arriving at the 3rd Annual Academy Museum Gala, where she was set to perform the award-winning song "What Was I Made For?", Eilish debuted her teeth grills, including full silver crowns and a star between her two front teeth. This latest accessory, paired with her new red roots, a tight suit dress and a hair scarf, is a testement to her ever-evolving style.

We've seen her in green roots, but more recently, the singer opted for red. Bright and bold, this new hairstyle is an accessory all on its own.

In the music video for Eilish's "What Was I Made For?", she made sure to channel Barbie. The bouncy blonde ponytail was the perfect ode to the beloved doll and even reminscent of Eilish's "Happier Than Ever" days.

After growing out her dark brown lob, Eilish sported the long-haired look, with soft, textured bangs to frame her face. At the premiere for Swarm, a Prime Video original in which Eilish made her acting debut, she leaned into this simplicity with straight hair, a white button down, and silver jewelry.

Eilish attended the 2023 Met Gala in a sultry, gothic gown which she elevated with smudged eyeliner, a long braid adorned with satin ribbons, and bejeweled barrettes. The singer has seemingly mastered the effortlessly edgy look.

To promote her second fragrance, Eilish No. 2, the popstar went for a wet look with smudged black liner and dewy skin. Her transition back into darker looks only proves her versatility.

For the 2022 Met Gala, where the theme was Gilded Glamour, Eilish arrived in a corset dress with a black ribbon chocker and dainty jewels. Her choppy updo gave the otherwise polished outfit a classic Eilish edge.

Taking to Instagram once again to debut a return to her dark-brown locks, Eilish proves the power of a hair transformation, and that style and beauty can evolve seamlessly in the span of one year. 

Promoting her new fragrance on Instagram, Eilish donned undeniably radiant skin, her staple glossy lip, and a soft gold shadow below the lower lash line. 

At the London premiere of No Time To Die, the James Bond film in which Eilish sings the theme song, the Grammy winner styled her bleach blonde bob in a choppy fashion and rocked gold leaf just beneath her brow for an added glimmer. 

An ode to Marilyn Monroe, Eilish attended the 2021 Met Gala in full Old Hollywood glam. Pairing an Oscar de la Renta gown with her sweeping blonde bob, bold black eyeliner, and a matte red lip, the singer-songwriter left her fans in awe. 

Taking to Instagram to debut a rugged bleach blonde chop earlier this year, Eilish never fails to surprise her devoted fans. Pairing a glossy lid with a soft pink pout, the singer-songwriter proves she can rock even the simplest of looks. 

For the promotion of her most recent album "Happier Than Ever" via Instagram, Eilish posted a host of photos in which she rocks glossy locks, a glossy peach lip, and highlighter visible from the moon. 

Masked up in pink and black, Eilish wore a pink and black floral suit with a matching manicure on the carpet of the 2021 Grammy Awards.

Coordinating her iconic green and black hair with her custom Gucci look, Eilish was the star of the show at the 2020 Grammy Awards. Taking home five awards over the course of the evening, Eilish not only won in the music department, but in the beauty department as well. 

For her attendance at the 2019 Sean Penn CORE Gala, Eilish paired soft blue-gray locks with her classic glossy lip and clean skin look. Known for her inclination to rock radical looks, Eilish can make even the boldest of hair colors appear effortless.
