Clothing Combat

This is basically using clothes as Improvised Weapons, proving that some people don't carry weapons because they wear them.

A Super-Trope to:
 * Armed Legs
 * Glove Slap
 * Power Fist
 * Shoe Slap
 * Weaponized Headgear

However, do not confuse the following as subtropes:
 * Nothing Up My Sleeve: This one is for those who hide actual weapons inside their otherwise-harmless sleeves.

Contrast Cloth Fu.

Anime and Manga

 * Master Asia of G Gundam, The Undefeated of the East, uses the sash he wears around his waist as a weapon. To absurdly lethal effect. He can turn it into a makeshift drill or whip and the thing appears to exhibit the properties of a steel blade... and this is when he isn't empowering it with his own ki. With this, he can destroy Mobile Suits while on foot. Remember, this is the man who taught Domon everything he knew. Yes, he's just that good.
 * In Ranma ½, Ryouga uses his bandannas as weapons, and once he used his belt.
 * In Berserk, Guts shields himself from arrows with his cloak.
 * Rurouni Kenshin: Hajime Saito use his friggin' belt to block, grab, lift, and almost kill Kenshin Himura in their first in-series battle.
 * Teppa Aizen in Grenadier can weaponize all his clothes (made of Applied Phlebotinum), altering their physical properties to those of a sword, a rope, a shield, etc..
 * In Mahou Sensei Negima, Kuu Fei uses a cloth spear in her fight against Mana, made from a sash in her dress.
 * In Kenichi: The Mightiest Disciple the Multi Melee Master Shigure is in a hot springs bath, completely naked and helpless. Surely, it's the right moment to attack her, right? Wrong! She can still use her hair ribbon (soaked in hot water) to defend herself, at least temporarily until she retrieves her sword.

Film

 * In Iron Monkey, the one villain uses a technique called "flying sleeves" in which the sleeves of his robe extend and he uses them to batter his opponents at range.
 * The Three Musketeers 1973: During a fight in a laundry, Athos loses his sword and picks up a piece of wet clothing to use as a weapon.
 * Each movie in The Transporter trilogy has at least one fight scene where the main character uses his trademark black suit to beat up or tie up his opponents. It's probably a complete coincidence that this inevitably leads to a Jason Statham shirtless scene.
 * In Hero, Flying Snow uses her sleeves to knock down barrages of arrows.
 * In Once Upon a Time in China III, the main character, in one scene, pacifies a street full of fighting ruffians by taking off his outer jacket and whipping it around with characteristic kung fu precision.
 * Mulan uses a sash to fight off some of the Huns in the Imperial Palace with the help of her friends Yao, Ling, and Chien-Po (dressed in drag) before her final confrontation with Shan Yu.

Literature

 * In the Mechwarrior: Dark Age novel, Service for the Dead, Anastasia Kerensky takes off her halter type garment and uses it to strangle her opponent in a duel for command of the Steel Wolves. Afterward, nobody bothers to question the crazy topless woman about the legality of using her clothing as a weapon in what was supposed to be an unarmed contest (though IIRC, her opponent grabbed a knife from an observer after she came at him with the shirt the first time).
 * Children of Dune featured a fight between Gurney Halleck and some mook. Halleck's strategy is to wait until the man lunges at him, then to throw his cloak over the guy's head and stab him through it.
 * Roger Zelazny's Amber series novel The Courts of Chaos. When Corwin fights Duke Borel of the title Courts, he runs away and sets an ambush. When Borel appears, Corwin throws his cloak over Borel's head, rendering him helpless just long enough to kick him off his horse and skewer him with his sword as he's removing the cloak.

Live Action TV

 * Weaponized sleeves are relatively common in Wuxia series, especially used by women fighters.

Real Life

 * Bullfighters
 * Rapier and Cloak is (or was anyway) a Real Life discipline, back when people walked around with cloaks and rapiers on a regular basis. It's still used when appropriate in Stage Combat, Society for Creative Anachronism, etc.
 * One type of eastern hidden weapon is a long-sleeved robe with weights sewn into the cuffs.
 * Lee style Tai Chi has an empty-hand form, and a number of weapon styles - duelling sword, broadsword, staff, nunchuks... and silk scarf.

 * 1st Edition supplement Oriental Adventures: one martial arts ability was Steel Cloth, which allowed a character to use a piece of cloth as if it were a spear.
 * Red Steel additional rules for fencing schools had using one's cloak to entangle the opponent's weapon ("Silk and Steel") as one of the basic maneuvers in a widespread Swashbuckler-oriented school.

 * One school of swordfighting in 7th Sea is basically "Cloak and rapier" (one in each hand).
 * Amber Diceless Role-Playing. Throwing a cloak or rug over someone's head is a specific form of attack listed under Weapons in the Other Factors in Combat section.
