The party’s tonight. You forgot. Or you were planning to “just wear a hat.” Either way, you need a costume, and you need it in the next hour.
Every costume here comes mostly from a regular guy’s closet: flannel, jeans, a white T-shirt, a suit. Each one lists the one cheap thing worth grabbing on the way if you’ve got time.
Jump to a Costume
1. Lumberjack
The fastest good costume for guys. A lumberjack is flannel, jeans and a beanie, and it looks better the bigger and beardier you are.
How to do it: Red flannel, jeans, boots and a beanie. Roll the sleeves. Suspenders if you have them. About 10 minutes.
Worth buying: an inflatable axe.
2. Greaser
White tee, jeans, slicked hair. A 1950s greaser is basically free.
How to do it: Fitted white T-shirt, cuffed dark jeans, boots, a leather or jean jacket with the collar up, and hair combed back with gel or pomade. About 15 minutes.
Worth buying: strong-hold pomade.
3. Cowboy
If you own boots and a plaid shirt, you’re a cowboy.
How to do it: Plaid or western shirt, jeans, boots, a bandana at the neck and your biggest belt buckle. The hat is the one thing worth buying. About 10 minutes.
Worth buying: a classic cowboy hat.
4. Zombie
The ultimate no-budget costume. Any outfit becomes a zombie if you ruin it.
How to do it: Old clothes torn by hand, dirt rubbed in, gray eyeshadow on your face and dark circles under the eyes. Pick a “before” job: zombie golfer, zombie office guy, zombie jogger. About 25 minutes.
Worth buying: washable fake blood.
5. Mad Scientist
A white button-down worn backward or a lab coat is a mad scientist.
How to do it: White shirt or lab coat, goggles or swim goggles, rubber gloves and hair sprayed straight up. Drop a glow stick in a water bottle. About 15 minutes.
Worth buying: a cheap white lab coat.
6. Secret Agent
Own a black suit? You’re done. The easiest sharp-looking costume there is.
How to do it: Black suit, white shirt, black tie, sunglasses and a curly earpiece (or a phone charger cord tucked behind your ear). Talk into your wrist. About 5 minutes.
Worth buying: a secret service earpiece.
7. 1920s Gangster
A dark suit and a fedora is a Prohibition-era gangster.
How to do it: Dark suit or vest and slacks, a loud tie, suspenders and a fedora. Pocket square. Slick your hair. About 15 minutes.
Worth buying: a classic fedora.
8. Pirate
Messy is the point. A pirate is a loose white shirt and attitude.
How to do it: Loose white shirt untucked, dark pants tucked into boots, a scarf at the waist and another on your head, and an eye patch. Smudge some eyeliner. About 15 minutes.
Worth buying: a pirate bandana and eye patch.
9. Punk
A band tee, ripped jeans and a jacket covered in safety pins is a punk.
How to do it: Black band tee, ripped jeans, boots, a leather or jean jacket with safety pins, and hair spiked with gel. About 15 minutes.
Worth buying: a pack of punk patches.
How to Make a Last-Minute Costume Look Intentional
Commit to one detail. The beanie, the pomade, the fake blood. A half-done costume looks like you forgot; a fully committed one looks like you planned it.
Buy the one thing people recognize first. The cowboy hat, the fedora, the earpiece. Everything else can come from your closet.
Stay in character a little. A secret agent who talks into his wrist all night is funnier than a guy in a suit.
