How to put it together

1
Choose your specific 'S' identity, such as a Spy, Skeleton, Sailor, or Scarecrow.
2
Gather the primary base garments, such as a trench coat for a spy or a flannel shirt for a scarecrow.
3
Add defining character accessories like sunglasses, a straw hat, or a white sailor cap.
4
Cut a large, clear letter 'S' out of colored felt or sturdy cardstock.
5
Attach the letter 'S' badge to your chest or sleeve using safety pins or double-sided fabric tape to emphasize the alphabet theme.
6
Finish the look with simple, character-appropriate makeup or props, like a magnifying glass for a spy.

Makeup & hair

Keep it simple and character-specific, such as messy hair and orange nose paint for a scarecrow, or sleek, combed-back hair and dark sunglasses for a spy.

Tips

Choose a character that is instantly recognizable so you do not have to constantly explain your costume to other guests.
Wear a literal letter S badge on your outfit if your chosen character is slightly obscure or niche.
Prioritize comfort by choosing everyday clothing bases like flannel, denim, or hoodies that suit the weather.
