Growing up in the 2000s meant growing up alongside some unforgettable characters. If you had posters on your wall, a specific Disney Channel lineup memorized, or a prized collection of American Girl Dolls, this Halloween is your chance to relive it all. The best part about building a nostalgic Halloween costume is that you don’t need a costume shop to do it. Goodwill’s shelves are full of the exact pieces you need to recreate your favorite 2000s girl icons, all while saving money and keeping sustainable, secondhand fashion in style.
Here are five throwback Halloween costume ideas that are easy to thrift in 2026, for nostalgia’s sake.
-
Hannah Montana and Miley Stewart
The best of both worlds deserves the best throwback Halloween costume. Hannah Montana and Miley Stewart is a fun go-to for 2000s girls who grew up belting out every lyric from the Disney Channel hit. This costume works solo or as a duo if you want to double the nostalgia with a friend. Thrift your way to Tennessee stardom with:
- A blonde wig to channel Hannah’s signature look, or Miley’s natural brunette locks
- A sparkly or sequined top
- Dark skinny jeans
- Platform boots or heels
- A guitar prop (or a hairbrush microphone for the Miley side of the look)
-
Dora the Explorer
Dora the Explorer is one of the most recognizable throwback Halloween costumes for anyone who grew up watching her solve problems with Boots and a trusty backpack. This nostalgic Halloween costume is simple, colorful, and endlessly charming. Search your local Goodwill for:
- An orange short-sleeved top
- Pink shorts
- A purple backpack
- A small handheld map prop
- Short pigtails or a wig to match Dora’s hairstyle
-
Tiana from The Princess and the Frog
Tiana remains a beloved figure for 2000s girls who dreamed of opening their own restaurant in New Orleans. Her story of ambition and heart makes this nostalgic Halloween costume feel just as meaningful today. Build Tiana’s look with:
- A green satin or silky dress (or a simple green gown you can accessorize)
- Gold jewelry or a thin gold headband
- White gloves, if you can find them
- Green flats or heels
-
Kit and Molly from American Girl Dolls
For many 2000s girls, Kit and Molly weren’t just dolls. They were companions. This throwback Halloween costume works beautifully as a duo or styled solo, with each doll offering her own distinct, nostalgic era. Thrift this historical pair with:
- Kit: A 1930s-style button-down blouse, suspenders or high-waisted trousers, and a newsboy cap
- Molly: A 1940s-style plaid skirt, a cardigan or sweater vest, and round glasses
-
The Cheetah Girls
Few throwback Halloween costumes capture 2000s girl energy quite like the Cheetah Girls. This nostalgic group costume is perfect if you and your friends want to relive the glitter, the harmonies, and the early-2000s fashion in one unforgettable look. Each Cheetah Girl, Galleria, Chanel, Dorinda, and Aqua, can bring her own flair, but the group look comes together with:
- Cheetah-print tops, skirts, or accessories
- Platform shoes or chunky sneakers
- Bold, colorful jewelry
- Sparkly or metallic fabric accents
- Confident, early-2000s styled hair
