Halloween Costume With a Blue Dress: 15 Ideas
A halloween costume with blue dress is one of the easiest closet costumes, because so many storybook and fairytale characters wear blue. A light blue dress plus a white apron and a headband makes Alice in Wonderland; a blue gingham-style dress with pigtails makes Dorothy; a royal blue dress with a crown becomes a queen; and a navy dress with pale makeup becomes a ghostly Victorian doll. Here are 15 ideas, organized by shade.
If you've got a blue dress and zero clue which character it's secretly auditioning for, The Costume Rack matches your closet and vibe to a costume in about two minutes: Start my costume.
Light blue dress costumes
Light blue dress costume ideas are the most fun because baby blue has such a clear storybook energy. (Quick note: the classic book characters below come from public-domain stories like Alice's Adventures in Wonderland and The Wonderful Wizard of Oz, so you're free to be them however you want.)
1. Alice in Wonderland
- Light blue dress, any length
- White apron (a white pillowcase cut open works)
- Black headband or ribbon
- White tights or knee socks, black shoes
- Prop: a teacup, a pocket watch or a playing card
2. Dorothy
- Blue and white checkered dress (or a plain blue dress over a white tee)
- Two pigtails with blue ribbons
- Red glittery shoes (or red socks, honestly)
- Prop: a small basket with a stuffed dog
3. Blue fairy
- Light blue dress, the floatier the better
- Paper or wire wings
- Glitter on cheekbones
- Prop: a wand made from a stick and a star
4. Cinderella-style ball look (pre-midnight)
- Pale blue dress, hair up, a headband or tiara
- Prop: one plastic "glass" slipper you carry around
5. Ice queen
- Pale blue dress, silver or white cape, snowflake clips
- White or icy makeup optional
Navy and royal blue dress costumes
Deeper shades read more serious and elegant. A navy blue dress costume or a royal blue dress costume works great for spooky or regal looks.
| Shade | Costume | Add this |
|---|---|---|
| Royal blue | Queen / princess | Crown, sash, big necklace |
| Royal blue | Superhero (original) | Cape, a logo you design, boots |
| Navy | Flight attendant | Neck scarf, name badge, a tiny wheelie bag |
| Navy | Sailor | White collar, a sailor hat, anchor pin |
| Navy | Victorian ghost | Pale powder, lace gloves, candle prop |
| Midnight blue | Night sky / starry night | Gold star stickers all over |
6. Queen
Royal blue dress, paper crown or tiara, a sash across your chest, and a "royal" attitude. Carry a scepter made from a wrapping-paper tube with a ball on top.
7. Sailor
Navy dress, a big white collar (cut from felt or paper), a sailor hat, red ribbon at the neck. Classic and cute.
8. Victorian ghost doll
Navy or dark blue dress, pale face powder, dark circles under your eyes, a lace collar. Stand very still in photos. Creepy in the best way.
9. Starry night
Midnight blue dress covered in gold star stickers, a moon headband. This one's easy and glowy, and if you have glow-in-the-dark stickers, even better.
Storybook blue-dress characters
Beyond Alice and Dorothy, blue shows up all over classic fairytales and nursery stories. A storybook costume with a blue dress is perfect for school costume days or book week (UK schools do World Book Day in spring, but the same builds work in October).
- 10. Little Bo Peep: light blue dress, white apron, a bonnet, a toy sheep, and a crook made from a stick.
- 11. Goldilocks: blue dress, curly blonde hair (or a yellow ribbon), and a bowl of "porridge."
- 12. Mermaid (land version): blue or teal dress, shell necklace, fishtail braid, glitter.
- 13. Witch (blue edition): navy or royal blue dress with a black witch hat and cape. A witch doesn't have to be black; blue looks moody and unexpected.
Deciding which of these fits the dress you actually have, and whether you want face paint, is the part that eats your evening. The Costume Rack does that match for you: two minutes on your vibe, closet and face paint, then a costume split into pieces with where to find each one. Start my costume
Blue dress group ideas
A blue dress group costume works when blue ties the group together.
Duo ideas
- Alice + White Rabbit: one blue dress, one white hoodie with bunny ears and a pocket watch.
- Dorothy + Scarecrow: one blue dress, one flannel with straw. (Our plaid skirt ideas include a scarecrow build that works here.)
- Day + Night: one in a yellow dress with a sun headband, one in a blue dress with stars. See our yellow dress costume ideas.
Group ideas
- Ocean crew: blue dress (the sea), a mermaid, a sailor and a pirate.
- Fairytale squad: Alice, Dorothy, Bo Peep and Goldilocks, all in blue with different props.
- Color squad: everyone wears a different color dress. Blue, yellow, red, green. Name yourselves after crayons or gemstones.
Accessories that make it read
A blue dress on its own is just an outfit. These halloween costume with blue dress accessories are what make it a character.

14. Blue dress + white apron
Honestly, a halloween costume with blue dress and white apron is so versatile it deserves its own number. Alice, Dorothy, Bo Peep or a dairy maid. Change the prop, change the character.
15. Black dress swap
No blue dress? A halloween costume with black dress works with most of the same ideas: black-dress witch, Victorian ghost, black cat. The props do the heavy lifting.
Your blue dress becomes a costume in two minutes
A halloween costume with blue dress should take one or two extra pieces, not a shopping trip. The Costume Rack asks about your vibe, what's already in your closet and face paint, then gives you a costume with pieces, a version made from things you own and three put-together steps. Tell it about the dress.
