If you grew up in the early 2000s, then Mary-Kate and Ashley Olsen were probably your style icons for a good chunk of that decade. You can easily recreate one of their early red carpet moments with a pair of flared jeans, a silky sequin tank, and some flats.

A list of jeans-based Halloween costumes wouldn't be complete without Britney Spears' and Justin Timberlake's all-denim ensembles that they wore to the 2001 AMAs. Back when the duo was the couple of the early 2000s, they changed the red carpet game forever with this matching Canadian tuxedo and gown combo. Grab your significant other or a friend and dress in head-to-toe denim to recreate this look.

Whether you like it or not, the Twilight resurgence has commenced since the series was added to Netflix in July 2021 — and it will absolutely spill over to Halloween. Bella Swan, queen of pained looks and jeans, is the simplest of all costumes. Throw on some gray jeans, boots, and an ordinary top, and you're ready to say it (vampire). Paint some teeth marks on your wrist to really sell the look.

There’s one theme in particular that is all but carrying the TikTok Twilight revival on its back: Jacob Black. More specifically, the werewolf’s “Where the hell have you been, Loca?” line. For this costume, you really only need a long black wig, a T-shirt, and jeans. And of course, use that iconic line every time someone returns from getting a drink or using the bathroom.

Kevin Hart understood the assignment when he turned a viral ‘90s photo of Dwayne “The Rock” Johnson into a legendary, albeit simple, Halloween costume. And while he may have been the first person to tap the potential of the infamous fanny pack portrait, he certainly won’t be the last. It’s just too good. And best of all — it’s one of the easiest Halloween costumes with jeans to recreate. Tuck a black turtleneck into belted jeans and clip a black fanny pack around your waist. Accessorize with a necklace, bracelet, watch, and a solo hoop earring, all in chunky silver.

Unleash your inner artist and dress like this peaceful painting legend for Halloween. All you need is a pair of jeans, a curly wig with a beard, and a blue button-down.

Texas Forever.

One of the easiest and most iconic couples costumes: Janet Jackson's and Tupac's characters as Justice and Lucky in Poetic Justice.

Ideally, you’ll have a short, curly blonde wig available, but curling your hair in tight ringlets works too. Wear old-school oversized reading glasses with jeans and write “Vote for Pedro” in red ink on a white T-shirt. Bonus points if you have a friend to be Pedro with you.

If you're in the mood to dance this Halloween, then dressing up as Baby and Johnny Castle from Dirty Dancing is a convenient and easily recognizable costume.

If you're celebrating Halloween as a trio, there are quite a few TLC looks incorporating jeans that you can choose from. To recreate one of their red carpet looks, all you need is baggy denim pants, oversized white T-shirts, and some spray paint to deck out your outfits in color.

Ever imagined what it would've been like to be Steve Jobs for a day? Well, you can at least (very easily) dress up as the co-founder of Apple for Halloween. All you need are a pair of straight-leg jeans, some worn-in New Balance sneakers, and a black turtleneck sweater. If you prefer a more feminine take on the look, pair the same outfit with a ponytail and red lipstick to channel Elizabeth Holmes, the former Theranos founder and CEO, whose ongoing trial is all over the news right now.

No one can rock acid wash denim quite like the cast of Saved by the Bell. Seriously, no matter what episode you watch, one of the cast members was most likely wearing a pair of acid wash jeans at some point. So if you have a pair of those, a brightly colored T-shirt or leotard, and a comb to tease your hair, you can successfully channel one of the characters from this '90s sitcom.

If you like Halloween more on the spooky side, consider being this character from the creepy Stephen King tale. Have a yellow raincoat? You’re pretty much all set — just add jeans, a pair of rain boots, and a red balloon. And keep away from storm drains if you know what’s good for you.

If you still find yourself playing "Pokémon Go!" then it's a no-brainer that you should be Ash Ketchum for Halloween. While Ash's outfit is relatively easy (all you really need is a pair of jeans, fingerless gloves, a T-shirt, and a trucker hat), you'll want to make sure to bring Pikachu around with you on Halloween.

If you're ridiculously clumsy like Urkel from Family Matters, then this easy costume is for you. All you need is a pair of high-waisted jeans, suspenders, white socks, loafers, and a button-up shirt (buttoned all the way up). Don't forget to say, "Did I do that?" periodically throughout the night to really embrace the character.

Good news for Mean Girls fans: You can dress like Cady Heron regardless of if you're doing a group costume or dressing up alone.
