No sewing, nothing that assumes a craft store is still open.
If: If it is already dark out

If Halloween is closer than you think, here is the whole build, word for word from the costume guide.
The pick: Banana
Real numbers: 10 min - Easy
You will need:
- Yellow sweatshirt and sweatpants, 1 set (make: from closet, or buy: clothing store)
- Green felt, 1 sheet 9x12 inches (buy: craft store)
- Headband, 1 (buy: dollar store)
- Fabric glue, 1 tube (buy: craft store)
- Put on the yellow sweatshirt and sweatpants.
- Cut a stem shape from green felt, about 4 inches tall.
- Hold the stem against the headband and check the position in a mirror BEFORE gluing, once fabric glue sets, the stem cannot be moved. Glue the stem to the headband and let it dry flat.
- Wear the headband. You are a banana.
- Optional pro finish: glue a small brown felt rectangle at the bottom front of the sweatshirt as the banana tip. Top and bottom details make it read as banana, not yellow sweats.

FAQ
What is an easy DIY Halloween costume for kids?
The Banana takes 10 minutes: a yellow sweatsuit and sweatpants plus a green felt stem hat on a headband. Underneath it is just pajamas, so it is the easiest costume a kid will actually keep on. The full step-by-step build is on this page.
What are good last-minute Halloween costume ideas?
The Classic Ghost takes 10 minutes: a white sheet, a thick black marker, and scissors. Cut the eye holes small first and trim the hem so it clears the ground. If you can make one store trip, the Glow Skeleton takes 20 minutes, and it glows so drivers can see your kid on dark streets.
What are good group Halloween costume ideas?
The Cereal Crew is the simplest group build: each kid becomes a different cereal box in 20 minutes. For the whole family, the Aussie Dog Family is blue and orange shirts plus paper ears on headbands, 25 minutes. Two sisters can do Snow Sisters: one icy blue dress, one pink, 30 minutes.
How much does it cost to make a kids Halloween costume?
Every pick on this page builds from household basics. If the shopping list is the whole question, the Cereal Crew needs one cereal box per kid and the Classic Ghost needs only a white sheet.
Can I make a Halloween costume the night before?
Yes, if you pick a build . The Banana and the Classic Ghost both take 10 minutes and nothing has to dry, so they work at 8pm on October 30. The Fuzzy Monster and Snow Sisters need glue or paint to dry, so start those a few hours earlier.
