Too cool to care

With only one debut single under her belt at the time, Billie showed up to the 2016 Teen Vogue Young Hollywood party in relative anonymity — but her outfit definitely turned heads. In an oversized t-shirt, camouflage cap, dirty sneakers and scuffed knees, the rising teen star definitely stood out amongst her glitzy peers.

Billie has us seeing (too much) green

Fresh off the release of her debut album, a bona fide commercial success, you'd have thought Billie would have been all smiles at Glamour’s 2017 Women of the Year Awards, but — true to her brand — the star kept her mood gloomy and her style grunge-chic, as she stepped out in an oversized green ensemble and matching fur-trim Gucci loafers.

Shocking no one in another oversized getup

True to form, the "bad guy" singer showed up to the ASCAP Pop Music Awards in 2018 rocking yet another bright and oversized outfit. We’re digging the monochromatic vibes, but it’d be nice to see the singer branch out beyond pieces that overwhelm her frame.

Keeping it neutral

So OK, it was much of the same for Billie at the Billboard Music Awards in 2019 — oversized and monochrome. But the neon roots and oversized aviator frames were definitely new…

Leaving us with so many questions

We're not sure where to start with this outfit from 2019. From the fit to the print, to the unnecessary turtleneck detail — it’s a lot. Why, Billie, why?

Trying a trench

So it’s not a huge style stretch, but it’s something. Billie kept it monochromatic for the 2020 Brit Awards (shocking no one), but she did incorporate a trench coat as part of her look — and dare we say, wore it in her size!

Sporting head-to-toe-prints

One thing’s for certain, no one rocks a bucket hat like Billie — and the matching mask was a nice touch. The look, worn at the Grammy’s, is both funky — and frightening, and we’re just not sure which way we’re leaning here…

She seems to be shedding those bulky layers and boldly stepping into a new, more mature, fashion phase. And clearly, we’re so here for it.
