Halloween costume ideas for sweatpants, leggings, comfy clothes

Halloween is just around the corner – so if you’re still looking for a costume, we’ve got you covered.

While it can be fun to dress up in pop culture-inspired costumes, many of us are feeling a little too lazy to put in the effort to change out of our sweatpants.

Especially after living in our comfy clothes throughout the pandemic, changing into something less comfortable doesn’t sound very appealing.

That’s why we’ve come up with a list of costume ideas that transform your athleisure into a costume – so you can look like you tried without really trying too hard (and while staying super comfy).

Costumes with sweatpants, leggings


Pop on a grey sweatsuit and some boxing gloves and you’re ready to knock out the costume competition with a Rocky Balboa-inspired look.

Aerobic workout

Transport back in time with a retro ’80s aerobic workout look. All it requires is a leotard (or a one-piece bathing suit), a pair of leggings and some leg warmers. And get ready to jazzercise!

Kim Kardashian

Style up your leggings like the Skims queen herself and be a Kardashian for a night. Anything monochrome works best – like Kim’s all-black look below, which can be replicated with a bikini top. Style you hair long and flowy (or get a wig that does the same) and tie it together with some heels.


Some call it basic, we call it classic. Nothing is easier than putting on some black leggings, a black long-sleeved shirt, a car-ear headband and painting on some whiskers to transform into a black cat for spooky season.

Costumes with gym shorts

Billie Eilish

If you want to go with shorts, no problem! Pop some on with a matching oversized sweatshirt and a green wig to look like the “Ocean Eyes” singer.

VSCO girl

Become the living meme by pairing Nike shorts with an oversized sweatshirt and scrunchies. Bonus if you accessorize with a Hydroflask to sip out of throughout the night.
