Billie Eilish Aesthetic
If you’ve ever watched a music video and thought, “Dang, Billie Eilish is a whole vibe,” you’re not alone.
Halloween is the perfect time to channel that edgy, moody energy she’s famous for. She’s basically carved out her own corner in music history, and the best part? Most of her looks are super comfy. Like, hello? Baggy clothes as a costume? Yes please.
A Billie Eilish costume lets you look cool and feel like you’re still in loungewear. Win-win.

It’s not just costumes though! We also love all the decorations we see in homes and yards, some amazing outdoor Halloween porch decor, and plenty more.

Billie Eilish Essentials

One thing about Billie’s looks, is that you may have a lot of outfit pieces that will work to help create the look. So shop in your own closet – or your boyfriends! A few key pieces will pull it together and you will totally have the look.
You can go full Bad Guy with that neon green wig and oversized attitude, or lean into one of her glam-but-still-goth spooky season red carpet moments. Billie is always on the list of most popular pop culture Halloween costumes for a reason. And with her new album heating up playlists again (Hit Me Hard & Soft at the time this post is being made), you’re in the right place if you wanna show out for your Halloween festivities or even a pop diva theme party, any time of the year.
Here are some of the essentials for a Billie costume:
The Hair
Signature Eyes
The other feature Billie Eilish is known for, and one that never changes, are her incredible blue eyes. We can’t help with the sanpaku look, but we can help you find blue contacts, in case you don’t have that gorgeous blue color naturally.
Check out this amazing website Moco Queen for all kinds of cosplay contact lenses, including this one called “Ash Blue” that remind us a lot of Billie’s blue hue.
The Nailssss
More often than not, she is rocking some seriously long nails. You can grab you a set here and go with any color you want!
From bold red carpet fits to the chill streetwear she rocks with a face mask (because Billie makes everything a lewk), there’s a ton of inspo.
Maybe go for a loose Lost Cause vibe, throw on a colorful wig, or recreate her debut album era hair with spray dye and attitude.
Grab a pair of chunky sneaks, pile on the silver rings, and don’t forget the long press-on nails.
Maybe go thrifting for a yellow sweatsuit, or style some cargo pants you already own, and then roll up with your group of friends all decked out in Billiefits.
How fun would it be for a whole group of friends to have a theme of different Billie Eilish looks!?! That is sure to be one of the best Billie Eilish Halloween costume ideas to win you Best Costume award at your next Halloween party.

We are going to split these looks up based on her hair color to make them easy to sort!
Black Hair Looks
The baseline. Her black hair looks are what we think of when we think of Billie Eilish’s natural color. Is it? We have no idea. But it looks so good on her, it may as well be.
