Green hoodie, felt spikes down the back, stuffed tail.
What Costume Can I Make With a Hoodie?
Short answer: the hood is the head. Whatever the hoodie color suggests, felt finishes. A green hoodie plus felt spikes taped and pinned down the back is a baby dinosaur in 20 minutes. A gray hoodie with one felt fin is a little shark in 25. A blue hoodie and two pipe cleaners make the blue alien in 30, and a set of colored hoodies with masks turns a whole crew into web heroes in 30. All four builds are no-sew: the extras attach with tape, safety pins, or paint, and the hoodie survives the night. Each card lists the real hands-on time and materials, with the full guide one tap away.

How any hoodie becomes a costume base
Pick by color first. Green reads dinosaur or alien, gray reads shark, blue reads alien or hero, red and black read web hero. The color does the first half of the job.
Add one felt shape. Spikes, a fin, or ears cut from a sheet of craft felt. One shape, big enough to read from across the room.
Attach without sewing. Tape the shape in place to test it, then pin from inside the hoodie so the pins hide. The Baby Dinosaur guide uses exactly this: tape first, then 6 to 8 safety pins.
Use the hood. Hood up, it carries the head of the costume. Hood down, it is just a hoodie again, which is why these builds work for kids who bail on hats and masks.

Questions, answered
Do I need to sew anything for a hoodie costume?
No. All four builds are no-sew. Felt pieces attach with masking tape and safety pins, the alien antennae are pipe cleaners, and the web hero look finishes with bought or felt masks.
Will pins or tape wreck the hoodie?
Safety pins leave pinholes you will not see after a wash, and masking tape comes off clean. The dinosaur build pins from inside the hoodie, so nothing shows in photos.
What is the fastest hoodie costume?
The Baby Dinosaur at 20 minutes of hands-on time: felt spikes down the back, tape, pins, and two stuffed socks for the tail. The shark takes 25 and the other two take 30.
What if my hoodie is the wrong color?
Every guide here lists a thrifted hoodie as a fine starting point, and thrift stores stock every color. Or flip the plan: a black hoodie is one of the bases for the Web Hero Crew.
