Ok, I am not typically a huge Halloween fan but I realized that some of my plus size girlies are still looking for last minute costume ideas. And, if you’re anything like me the thought of ordering costumes online last minute can seem pretty daunting. Even though, it’s a little late in the game, fear not we’ve got you covered. Here are a few of my favorite looks (most are via Amazon) that are guaranteed to arrive before Halloween hits.

Last Minute Plus Size Halloween Costumes
Should you go with something scary? Sexy? Somewhere in between? Should you dress up with your besties, or just DIY a witch outfit and call it a day? And finally, do you really need to buy an actual costume, or can you get away with throwing together a cheap last-minute outfit from items you already own?
The beauty of Halloween is that there’s no one right way to do it. You can go all out with a full plus size Halloween costume, or you can get creative with what’s already in your closet. Either way, these ideas will help you feel confident and festive without the stress.

Catwoman Costume
A classic! Grab a sleek black bodysuit, some cat ears, and dramatic eyeliner. Pair it with black boots or heels. It’s sexy, mysterious, and you probably already own half the outfit.
Witch Vibes
You can never go wrong with a witch. A long black dress, a pointy hat, and maybe a broomstick will have you looking festive in no time. Bonus: throw on a leather jacket and boots for an edgier twist.
Rosie the Riveter
This is a quick DIY costume that only requires a denim shirt, jeans, and a red bandana. Tie your hair up, flex your arm, and you’ve got an empowering plus size Halloween look that’s comfortable and iconic.
’80s Aerobics Instructor
Think neon leggings, an oversized sweatshirt, leg warmers, and a high ponytail. Amazon has plenty of fun neon accessories if you want to add more flair. This one is playful, colorful, and easy to throw together.
Wednesday Addams
The perfect spooky-cute look. All you need is a black dress with a white collar, black tights, and some braids. Simple but instantly recognizable.
Goddess Costume
Channel your inner Greek goddess with a flowy white dress, gold belt, and metallic accessories. Many versions are available online, or you can DIY with pieces you already own.
Flapper Girl
Go back to the 1920s with fringe, pearls, and a headband. It’s a glamorous, fun, and comfortable option that looks great on everyone.
Pirate Queen
Grab a flowy blouse, corset belt, and boots. Add a toy sword or bandana for extra detail. Plus size pirate costumes are easy to find on Amazon and make for a fun group option too.
Vampiress
Nothing says Halloween like a dramatic vampiress look. Long black or red dress, dark lipstick, and maybe a cape. Pair it with a smoky eye and you’re good to go.
Cowgirl Chic
A western vibe is quick to throw together—jeans, a plaid shirt, boots, and a hat. Add a bandana and you’re ready for the Halloween rodeo.
Barbiecore Pink
Since Barbiecore is trending, this is a perfect last-minute costume. Grab your favorite pink dress, heels, and accessories. Throw in oversized sunglasses for that extra Barbie sparkle.
Ghost with a Twist
Go beyond the classic white sheet—cut out the eyes, but wear fun accessories like sunglasses, a leather jacket, or even carry a pumpkin bag for personality.
Pop Culture Moment (Taylor Swift Eras, Beyoncé Renaissance, etc.)
If you’re into pop culture, Halloween is the perfect time to recreate one of your fave celeb looks. Sequins, glitter, or a bold outfit from your closet can transform you into a star for the night.
Wrapping It Up
Halloween is the time of year to play, experiment, and dress up in ways that let your personality shine. Whether you’re into scary, sexy, or silly, these last minute plus size Halloween costumes will make sure you feel confident and festive without the stress of waiting weeks for shipping.
