ABOUT DEBBIE THORNBERRY:
Debbie Thornberry is the older, sarcastic, eye-rolling teen sister we all either were—or were annoyed by. With her disheveled blonde waves, flannel shirts, and general air of teenage indifference, she brings peak 90s slacker energy to The Wild Thornberrys.
Whether she’s blasting alt rock in the family van or complaining about the lack of Wi-Fi in the jungle, Debbie’s iconic attitude and effortlessly cool outfit make her a classic throwback costume with serious edge.
1. ORANGE CROP TOP – Debbie’s signature midriff-baring orange tee is a must. Keep it fitted and slightly grungy to stay true to the character.
2. GREEN FLANNEL OVERSHIRT – Throw on an oversized green plaid flannel—worn open, obviously. It adds to that “whatever” vibe she rocks 24/7.
3. LONG BLONDE CRIMPED WIG – Debbie’s voluminous crimped hair is legendary. Go for a long blonde wig with waves or crimps to nail the look.
4. WIDE-LEG BLUE JEANS – A relaxed fit is essential. Think ‘90s baggy denim with attitude, bonus if they’re slightly distressed.
5. DARK LIPSTICK – Debbie’s no-makeup-makeup includes a moody maroon or deep plum lip. It’s subtle rebellion, in a tube.
6. GRAY SNEAKERS – Slip into chunky, no-fuss gray sneakers. They’re practical, like Debbie’s mood, and they’ll keep you comfortable while you silently judge everything.
If you’re the kind of person who rolls their eyes at family group chats and refuses to pretend to enjoy camping, Debbie Thornberry might just be your Halloween alter ego.
This is the ultimate low-effort, high-attitude costume. With a few throwback basics and a don’t-care demeanor, you’ll be rocking Debbie’s “bored in the jungle” energy in no time.

The Wild Thornberrys Costume Collection
Debbie wears an orange crop top beneath an oversized green plaid shirt, which she leaves open. Baggy distressed jeans, black lace-up shoes and long blonde hair complete her grunge-inspired 1990s outfit.
Layer any green plaid flannel over an orange tank top or cropped T-shirt. Add loose blue jeans, black shoes and dark lipstick, then carry headphones to make the character easier to recognize.
Debbie has very long, voluminous blonde hair with loose waves or a slightly crimped texture. Wear a long blonde wig with side-swept bangs or add texture to your natural hair using braids, rollers or a crimping tool.
Use chunky black headphones, a portable music player, dark maroon lipstick and bubble gum to capture Debbie’s bored teenage attitude. These details are particularly useful because her clothing can otherwise resemble an ordinary 1990s outfit.
Debbie learns about Eliza’s ability during The Wild Thornberrys Movie. She is allowed to keep the knowledge but is warned that she will be turned into a baboon if she reveals Eliza’s secret.
Pair Debbie’s blonde grunge outfit with Eliza’s yellow dress, red turtleneck, braided red hair, glasses and braces. Nigel, Marianne, Donnie and Darwin can be added for a complete Wild Thornberrys family costume.
