Some people just don't carry weapons into their fights - not because they actually fight with bare hands, but because their armoury have actually been incorporated into their normal clothing. The use of such clothing is not limited to the functions of Rule of Cool, but it also gives the wearer a pass in places where weapons are not normally allowed, since the weapons in question are all but invisible to casual observers.
Subtrope to Hidden Weapons. Sometimes overlaps with Improbable Weapon User. Compare Clothing Combat, where the actual piece of the clothing's fabrics can be used as a weapon; Clothes Make the Superman, where the clothing is responsible for the character having superpowers; and Powered Armor, where a suit of armor enhances a character's abilities.
Supertrope to the following:
- Gunsmith Cats: Bean Bandit's outfits.
- One Piece: Diamante of the Donquixote Pirates wears a cape that's actually a steel plate thanks to his Devil Fruit ability, which allows him to soften solid objects, turning them flexible and weightless, but keeping other natural characteristics like strength and toughness.
- In Brave10, both Rokuro and Nanakuma hide their combination whip/rope darts as part of their clothing. Surprising, given there's not much there to begin with.
- Baki the Grappler includes a very grisly example with the villain Hector Doyle, a serial killer escaped from death row. Doyle has several boxcutting razors fixed to the inside of his shirt collar, so when an opponent grabs him by his collar he shreds his fingers.
- Lady Killer from The Strangers in The Ultraverse is a superhero who's also a fashion designer. Every part of her costume can be used as a weapon.
- Batman's cape is weighted for use in attacks.
- Peacemaker, in the original Charlton incarnation at least. Almost every element of his costume was some kind of explosive or incendiary, though he was never shown actually using these.
- Robin: Tim modified his cape so that when it detached he could push a button and it would wrap around and cling to whatever was touching it, which made it a convenient way to take down and detain mooks while fighting.
- Doom Patrol: Codpiece was told that he wasn't big enough in High School, and though the girl who said it meant his height, he thought she meant his... penis. Due to an inferiority complex about the size of his wiener, he created a suit with a codpiece weapon system and became a supervillain. Yes, you read that right: his primary weapon is a weaponized codpiece.
- Four Deadly Secrets has a few.
- Melanie's new weapon is a set of elbow-blades which can be coiled up and hidden.
- A Faunus gang-member shows a belt which doubles as a dust-powered Whip Sword.
- The Looking-Glass Wars series: The entire Millenary, but Hatter Madiagan's wardrobe in particular.
- Adorabell Dearhart, AKA "Spike", AKA "Killer", has stiletto heals that can punch through two reinforced layers of cured leather and a human foot and still embed themselves into an oak floor board.
- Sam Vimes butler Wilkins used to own a hat with Sharpened pennies sewn into the brim for fighting; when he was a street ruffian in his youth.
- Granny Weatherwax is never seen without her pointy black hat, held on with several hatpins that she uses as weapons in the rare cases she needs a weapon at all.
- A Series of Unfortunate Events: Esmé Gigi Geniveve Squalor, in The Hostile Hospital, wears stiletto shoes with thin knives for heels.
- Lexx: His Divine Shadow's personal garments as well as apparently being made out of nano-machines allow his current host to fly and fire deadly sheets of pure energy from its entire surface.
- Minor example: The Fourth Doctor once covered a Dalek's eye-stalk with his hat, and sometimes used his long, trailing scarf to trip his opponents or tie them up.
- Shadowrun. The 2nd Edition supplement The Neo-Anarchists' Guide to Real Life had a section dedicated to armor and weapons disguised as clothing. They included the Barton Arms Bracer (a gun disguised as a piece of jewelry) and the Barton Arms Gun Cane (a cane that can fire a bullet). A variety of fashion houses (Armante, Mortimer of London, Vashon Island and Zoe) have formal wear that could stop a bullet.
- D&D : Monks; everything they wear can be used as a weapon.
- Munchkin Impossible, the Spy Fiction set, has the Shooty Hat. It's a gun hidden inside a hat.
- Hades in Kid Icarus: Uprising.
Viridi: He's covered from head to toe in weaponry. Like a rainbow apocalypse.Hades: I prefer to think of it as my devastation ensemble. I only wear it for very special occasions. You know, weddings, armageddons...
- In Malicious, the story revolves around a boy or girl called a Spirit Vessel, that have been charged with protecting humanity with scarfs that shapeshift into weapons called Mantle of Cinders. With that, they have to stop a great evil called '"The Malicious"', from destroying the world.
- Cerebella of Skullgirls, wears a monster-hat named Vice-Versa, that acts as the muscles and Cerebella as the knives.
- Several of the multiplayer personas in the Assassin's Creed disguise their weapons as attire. For example, one female has blades in her paper fan, and another stabs removes her Hair Decoration and stabs people's eyes with the metal prongs. Makes sense, because the multiplayer is assassins assassinating other assassins (and trying not to be assassinated themselves) in an assassination training simulator, so they have every reason to go covert.
- In Schlock Mercenary, the standard uniform for Tagon's Toughs is actually nanofiber armor with a deployable breathmask and allows antigrav flight as well. The uniform that Legs uses also has a pair of cannons built into the helmet, as she lacks humanoid hands with which to hold a weapon.
- Batman: The Brave and the Bold: In "Joker: The Vile and the Villainous", the Weeper has a handkerchief that can be used as a sword and a lasso (amongst other things).
- In one episode of Adventure Time, Finn and Jake repair a shoe for a funeral atendee with a magic nail. This causes it to sprout a knife from the toe, axes on the side and lassos from the laces.
- The Asiatic practice of making 'weighted sleeves'.
- Ninjas did this sort of thing constantly.
- There are kinds of high-heeled shoes that can be used this way.
- Razor blades or sharpened pennies sewn into a hat-brim are a traditional way of giving yourself an edge -literally- in a Bar Brawl, especially in the less salubrious parts of urban Scotland.
