Vance's longcoat outfit

 can be obtained from Vance in Meresti Metro Station and can be repaired with Leather Armor.

Obtaining
Vance's Longcoat Outfit can be obtained by killing Vance, Reverse-Pickpocketing or by using the Mesmetron weapon.
 * Killing Vance will make all other members of The Family hostile. Killing any of them will also make the residents of Arefu hostile, if Blood Ties was completed peacefully before.
 * Using the / command(s) on Vance in the console will also make the The Family and the residents of Arefu hostile towards the player as noted directly above.
 * If you use the Reverse-Pickpocketing technique to obtain it, you must use something with a higher damage resistance (11) than the Longcoat Outfit. This method will cost -10 Karma.
 * You can also use the Mesmetron to have Vance go berserk and get him killed by the rest of The Family. After Vance has been killed you can loot his corpse for his Longcoat and anything else he was carrying. You won't gain negative karma using this method.
 * The strangest way, and probably most exotic way to kill Vance and get his longcoat is to pick up some of the empty barrels, put them in between you and Vance, pic them up, and smush them into you and Vance. This takes a long time to kill him, and when you do, the Family and Arefu become hostile without the message coming up.
