Costumes That Start With S (Fancy Dress Ideas Too)
Skeleton, scarecrow, spider, superhero, sailor, scientist and sheep are the go-to costumes that start with S, and most of them come together from a black top, some tape or a flannel shirt. S is one of the best letters to get: it has spooky, funny and zero-effort options. Here's the full list, sorted by what you've got time for.
If you know you want an S costume but you're stuck turning it into an actual outfit, The Costume Rack breaks costumes like the skeleton into pieces and shows a version made from your own closet. Start my costume
S costumes you can make tonight
These need nothing you don't already own. Pick one, get dressed, go.
Skeleton
The king of costumes that start with S. Black long-sleeve top and black leggings or joggers, then bones in white.
- Tape version: white electrical or masking tape for ribs, arm bones and leg bones. Ten minutes.
- Paint version: white fabric paint on an old black top.
- No-makeup version: skip the skull face, pull up a black hood, and let the body do the talking.
Scientist
White shirt or lab coat, safety goggles or big glasses, a pen in your top pocket, messy hair. Carry a water bottle with green food coloring as your "experiment."
Sailor
Navy and white stripes or a white top, navy trousers, a white hat. Draw a tiny anchor on your arm with eyeliner if you want.
Sports star or ski instructor
Any jersey plus a headband is a sports star. A puffer, goggles on your head and a beanie is a ski instructor, which is also the warmest S costume on this list.
Student (the chaotic one)
Hoodie, lanyard, a coffee cup, bags under your eyes, a highlighter behind your ear. Perfect for uni: you're dressed as yourself, but on purpose.
Surfer
Board shorts or a wetsuit top, flip-flops, sunglasses, a "surfboard" made from cardboard. Hair messy and "salty."

How to make a spider costume
- Wear all black.
- Stuff two pairs of black tights with plastic bags or old socks.
- Safety-pin them to the sides of your top so they hang like legs.
- Add a web drawn in white on your top or a hair clip with a plastic spider.
How to make a scarecrow costume
A flannel shirt, jeans or overalls, a straw hat or beanie, and straw (or yellow paper strips) poking out of your cuffs and collar. Draw on stitches with brown eyeliner, or skip makeup and pin a paper patch on your knee.
Funny S ideas
This is where fancy dress beginning with S gets unhinged, in the best way.
- Sushi roll: black top, white fluffy scarf or pillow wrapped around your middle, orange paper "salmon" on top.
- Sloth: brown hoodie, move very slowly all night, refuse to leave the sofa.
- Smartie (UK) / Skittle (US): a single color outfit with an "S" or "M" on your chest. Group version below.
- Social media influencer: ring light (phone torch), filming everything, saying "hey guys" before every sentence.
- Sheep: white fluffy jumper or hoodie, cotton balls stuck on, paper ears. Say "baa" when you disagree with something.
- Snowman: white clothes, three black buttons, orange paper carrot nose, a scarf.
- Sandwich: two cardboard slices of bread worn like a sandwich board. Add a lettuce collar.
- Sunburnt tourist: red face (optional), socks and sandals, a map, a bum bag (UK) / fanny pack (US).
- Spam email: a shirt covered in "YOU HAVE WON" and "Dear Sir" notes.
- Sleepwalker: pajamas, eye mask, arms out, bumping gently into things.
S group ideas
Group costumes that start with S are easier than most letters because so many of them are groups already.
- Skittles / Smarties: everyone wears a different solid color with an "S" on the front. Cheapest group costume ever.
- Seasons: spring (florals), summer (sunglasses), autumn/fall (flannel, leaves), winter (puffer and scarf). Four people, done.
- Skeleton crew: everyone in black with bones, one person as the "captain" in a pirate hat.
- Spice rack: each person wears a paper label (salt, sage, saffron, sriracha).
- Superheroes: everyone creates their own hero with a letter on a tee and a cape from a blanket. No licensed characters needed.
- Sailors: stripes and white hats for the whole crew.
- Secret agents: black outfits, sunglasses and earphones as earpieces for the whole squad.
Couple costumes that start with S: salt and sugar, sun and sky, skeleton and specter, surfer and shark. For more duo energy, see opposite costume ideas.
The classic S group fail: four people go as skeleton because it's the easiest one. If your group sends each other one link on The Costume Rack, everyone claims a costume on the same rail and sees the skeleton is already taken before they buy any tape. Start my costume
