Tenpenny's suit

 is a piece of clothing found in Fallout 3 worn by Allistair Tenpenny of Tenpenny Tower. It can be looted from his body upon killing him.

Obtaining

 * If you sided with Tenpenny during the Tenpenny Tower quest there is still a way to obtain his suit nonviolently. Wait until he has started sleeping, then use a  Stealth Boy to reverse pickpocket a Grimy Pre-War Businesswear into his inventory.  Leave the building and return to find him wearing it, then pickpocket Tenpenny's Suit from him.  This only works if the suit given to him is of both better condition and better armor rating than his own.
 * If you have done the quest Tenpenny Tower and helped the ghouls to get into the Tower, Tenpenny will be dead after a certain amount of time.

Bugs

 * If you drop Tenpenny's Suit and then lift it up (using the Z-key or right bumper button) you may experience that the suit is now spinning round and round in the air.
