Do you ever feel like all your favorite celebs are hanging out without you, like at Coachella or NYFW? Then you probably noticed that a few weeks ago, an epic rager happened where, like, every single person you follow on Snapchat was invited.

Nicole Richie threw the most amazing themed birthday party, where everyone from Jessica Alba to Rachel Zoe was in attendance — and in fierce costumes. The ‘70s is definitely the decade of the moment, but with a few simple styling hacks you can take some wearable separates and pair them together for a groovy disco look. Oh, and everything’s under $100!

Tuck a red plunging bodysuit into a pair of gold lamé pants and add some chic accessories for a disco-fied look. You can wear the pieces separately too — the bodysuit would look great with some high-waisted flared jeans on the weekend, and the gold lame pants are just the kind of wake-up call your work wardrobe has been asking for.

The jumpsuit started out as a costume-y ‘70s look, but it’s now embraced fully as just a really cool alternative to a dress. Add a satin bomber for chilly nights, and mix your metals for a truly Saturday Night Fever-worthy moment. Pin-straight hair or natural curls complement the look.

Sometimes, it’s all about the subtleties. This liquid metal tee and pleated skirt from Topshop are a pairing you could get away with in real life — but could also wear to your next disco-themed party. The black platforms will get a lot of wear this season in general, and simple accents like a skinny scarf, nude bag and rhinestone earrings can be broken up into your everyday looks.
