Halloween sneaks up fast — one minute you’re sipping pumpkin spice lattes in the Phoenix sunshine, and the next you’ve got a party invite with no costume planned. But don’t stress! You don’t need to order something online or settle for a flimsy, overpriced outfit that doesn’t fit your curves. At Billie & Lulu’s, we know that Halloween should be fun, affordable, and inclusive — which is why we’ve put together some last-minute plus-size Halloween costume ideas you can pull together with pieces from your own closet or with a quick trip to our Phoenix plus-size boutique filled with secondhand treasures in sizes XL–6X.
Here are a few curvy-approved ideas that are easy, stylish, and comfortable — because spooky season should never mean sacrificing confidence.
1. The Classic ’90s Witch
All-black everything never goes out of style. Grab a black dress, layer on a wide-brim hat, and add dark lipstick for instant witchy vibes. Bonus points if you add fishnet tights or chunky boots from our secondhand racks. It’s timeless, curvy, and effortlessly cool.
2. Rosie the Riveter (Feminist Icon Chic)
This one is a plus-size win because it’s built on basics. Slip into high-waisted jeans, roll up a chambray shirt, and tie a red bandana around your hair. Add a confident “We Can Do It!” pose and you’re ready to rule the costume contest.
3. The Glam Fortune Teller
Layer a flowy skirt with a patterned shawl or kimono, add plenty of jewelry, and carry a deck of tarot cards. This look is all about drama and fun textures — and it’s easy to pull together from secondhand finds. Curvy silhouettes shine in this costume because it’s all about boldness and flair.
4. Wednesday Addams (with a Twist)
A black dress layered with a white collared shirt underneath gives you instant Wednesday vibes. Add braids, black tights, and a sassy “don’t mess with me” face. For a fun twist, make it “Adult Wednesday” with platform boots and dark lipstick.
5. The Pumpkin Patch Cutie
Not into spooky? Go sweet instead. Pair an orange dress or top with green accessories (think scarf, cardigan, or earrings). Add a headband with a felt “stem” or green bow for an easy DIY pumpkin look. Perfect for handing out candy or hitting the pumpkin patch.
6. Your Favorite Pop Culture Character
From Barbie to Bridgerton, secondhand racks are full of treasures you can use to recreate iconic looks. A pink dress and sparkly heels? Hello, Barbie. A vintage-inspired gown with pearls? Instant Bridgerton. With a little creativity, plus-size secondhand fashion makes these characters accessible for curvy babes.
7. The Retro Pin-Up Housewife
Channel your inner 1950s diva with a fun, campy retro housewife costume. Think a full skirt, button-up blouse (cinched at the waist with a belt), pearls, and a playful wig or vintage-style curls. Carry a laundry basket or feather duster for a cheeky prop, and you’ve got a look that’s nostalgic, fabulous, and body-positive. The best part? You can find almost everything for this costume secondhand — and reuse the pieces year-round.
