15 Halloween Costumes Made From Clothes You Own

The fastest Halloween costume is the one already hanging in your wardrobe. A black polo neck and black trousers becomes six different characters depending on what you add. A trench coat and a notebook is a detective. A slip dress and a pair of trainers is a runaway bride. Below are fifteen costumes built entirely from clothes most people already own, sorted by how little you need to buy, with the exact garment list for each.

Start with what you own, not with an idea

Most last-minute costume panic comes from picking the character first and then discovering you own nothing that looks like it. Reverse the order. Open the wardrobe, find the three most distinctive things in it, and work outwards from those.

The pieces that do the most work are a black polo neck, a trench coat, a denim jacket, a red or leopard-print anything, a satin slip dress, a blazer, and sunglasses. If you own four of those seven, you own at least ten costumes.

This is much easier if you can see everything at once. If you have already photographed your wardrobe into Wdrobe, you can scan it by colour in about a minute instead of pulling half the shelves out at nine in the evening.

15 costumes from clothes you already own

All black, six ways

Black polo neck plus black trousers plus black boots is the base. From there:

1. Cat burglar. Add a black beanie, a thin belt and a small crossbody bag. Draw on a nose and whiskers if you want it read instantly.

2. Beatnik poet. Add a beret, dark sunglasses, a paperback in your hand.

3. Mime. White face, a striped top if you own one, black gloves.

4. Spy. Add the trench coat, dark sunglasses and an earpiece.

5. Stagehand. Add a lanyard, a torch and a roll of tape. Underplayed, and nobody else will be it.

6. Shadow. All black plus a black cap and a matte finish. The joke is that you are someone else's shadow, so pick a friend and follow them.

Coats and jackets carry a costume

7. Detective. Trench coat, a shirt, dark trousers, a small notebook and a pen behind the ear. Belt the coat rather than buttoning it.

8. Greaser. Leather jacket, white tee, dark jeans, hair pushed back. A comb in the back pocket finishes it.

9. Explorer. Khaki or olive jacket, boots, a rucksack, a map folded wrong.

10. Scarecrow. Denim jacket or a checked shirt over a plain top, straw-coloured scarf at the neck, stitched-mouth makeup. The clothing does almost nothing here, the face does it all.

Dresses and skirts

11. Runaway bride. A white or cream slip dress, trainers, hair half falling down, a bunch of flowers held upside down.

12. Sixties girl group. A shift dress, a thick headband, flats, heavy eyeliner.

13. Wednesday. A black dress with a white collar, black tights, flat shoes, two plaits. If you have no collared dress, wear a white shirt underneath a black pinafore or slip dress.

14. Statue. A cream or grey dress, grey or white tights, grey makeup, and no movement while anyone is watching.

15. Devil in the details. A red dress or a red jumper with black trousers, plus horns. The only bought item in the entire list, and they cost almost nothing.

Make it read as a costume, not as an outfit

The difference between a costume and getting dressed is usually one exaggerated element. Three things do it cheaply:

• Headwear. A beret, a cap, a headband, horns, ears. It is the first thing people look at.

• Makeup. Whiskers, a stitched mouth, grey skin. It costs nothing and it reads from across a room.

• One prop you carry. A notebook, a torch, a bunch of flowers, a single glove. Pick something you can put down, because you will be holding a drink.

Avoid the trap of adding a fourth and fifth signal. Two strong signals read clearly. Five read as a fancy dress shop.

Check it before the night, not on the night

Put the whole thing on for ten minutes a few days before. Sit in it, walk in it, and look at it in a photograph rather than a mirror, because a costume lives or dies in photos. Check what happens when you put a coat on over it, since most of the night in October is spent either outside or queueing to get in.

If the costume relies on a jacket you have not seen since March, find it now. This is the part saving the outfit in Wdrobe genuinely helps with: you build the look once, keep it, and next October you are not rebuilding it from memory.

Frequently asked questions

What is the easiest last-minute Halloween costume from your own clothes?

All black plus one signal. A black polo neck, black trousers and a beanie is a cat burglar in ninety seconds, and adding a beret and sunglasses instead makes it a beatnik. Nothing else in your wardrobe converts this fast.

What Halloween costume ideas work for ladies with no shopping?

A slip dress worn with trainers and flowers reads as a runaway bride, a shift dress with a headband reads as sixties, and a black dress with a white shirt underneath reads as Wednesday. All three use clothes that are already in most wardrobes.

What can I wear if I do not want a full costume?

Wear your normal going-out clothes in black or deep red and add one thing: horns, cat ears, dark lipstick or a single dramatic accessory. See what to wear to a Halloween party without a costume for the full version of this.

How do I keep warm in a costume in October?

Build the costume so a coat can go over it, or so the coat is part of it, which is why trench and denim jacket costumes are the practical ones. Opaque tights under a dress and boots instead of flats buy you several hours outdoors.

If your costume needs a specific coat and boots, the same layering thinking applies as in any fall layering outfit, and the colour pairings in outfit colour combinations will tell you what your one red piece can sit against.

Fifteen ideas are useless if you cannot remember whether you still own the trench coat. Wdrobe puts your whole wardrobe on one screen so you can build the costume from what is actually there, then save it for next year. Put the costume together tonight instead of at six on the thirty-first.
