Quick Answer: The Tilly Green costume comes down to the purple Peter Pan collar dress and the black bob wig with bangs.
  • Light Purple Peter Pan Collar Dress (essential)
  • Short Black Bob Wig (essential)
  • Bunny Teeth (essential)
  • White Socks
  • Green Flat Shoes

Tilly is a farm kid who moved to the big city with her family and treats every strange new thing about the move with total, cheerful confidence. The purple dress with the white collar and the black bob wig together are what make this read as her specifically. Big City Greens airs on Disney Channel and streams on Disney+ (Wikipedia), so this costume is a strong pick for families and younger viewers but genuinely niche outside that audience.

How to Style the Tilly Green Halloween Costume

The bob wig is what people notice right after the dress, and without the sharp bangs and blunt cut, this reads as any kid in a purple dress at the party. Even at a crowded event, the bunny teeth are a small enough detail that people might miss it from a distance, so it matters more in close-up photos than across a room. The dress itself is comfortable enough that a young kid can wear it for a full night without complaining, which is not true of every costume on this site.

Tilly meets every new, strange thing about city life, talking dogs, giant buildings, her family’s chaos, with the same wide-eyed enthusiasm she’d bring to a farm chore back home. That is the energy to bring: cheerful, unbothered, genuinely delighted by things that should probably be alarming.

Trim the wig bangs if they’re too long out of the packaging

Costume wigs often ship with bangs cut longer than Tilly’s actual blunt, short style. A quick trim before the party makes a noticeable difference in how recognizable the wig reads.

Buy a spare set of bunny teeth if this is for a young kid

Kids lose small accessories fast, and a missing tooth piece halfway through the night is an easy fix if you packed a backup. Not worth scrambling for a replacement mid-party.

Tilly Green Group Halloween Costume Ideas

Family Idea

Tilly, Cricket & Bill Green

Strong family group if everyone commits, since the Green family is the whole premise of the show. Cricket’s look is simple, a green shirt and messy hair, which makes him an easy costume for a sibling or parent to pair alongside Tilly.

Sibling Duo

Tilly & Cricket Green

Strong sibling pairing and probably the easiest version of a Big City Greens group costume, since it only needs two people and both looks are simple to assemble. Works well for siblings or friends who want a coordinated but low-effort option.

Group Idea: Disney Channel Farm Kids

Tilly & Other Disney Channel Animated Characters

Might work, but it needs a crowd that watches current Disney Channel programming specifically, since pairing Tilly with characters from other shows only lands with people who know both series.

Tilly Green Halloween Costume DIY Tips

Building the Look

This is one of the simpler kids’ costumes on the site to put together, with only two items worth ordering ahead of time.

  • Dress: order this first, the specific purple shade and collar shape matter.
  • Wig: buy this, matching a natural haircut to her exact bob is unreliable.
  • Socks and shoes: check your closet before buying anything new.
  • Bunny teeth: cheap and worth it, this is the detail people look for.
  • Buy a spare set of teeth if this is for a young kid who might lose one.

Playing Tilly at the Party

Tilly treats everything new with wide-eyed enthusiasm, never embarrassed, never fazed.

  • If someone asks who you are, explain it like you are genuinely excited they asked.
  • She is not sarcastic. Keep the energy sincere and upbeat the whole night.
  • Bring farm-kid energy to city-party situations, mild confusion, total confidence anyway.
