Naughty nightwear (Fallout 3)

Naughty nightwear is a set of leopard skin pajamas found during the unmarked quest Grady's Package in Fallout 3.

Characteristics
A skimpy set of leopard-print négligée, the naughty nightwear provides a bonus of +10 to Speech and +1 to Luck, but is poorly suited to stopping laser bolts or rifle rounds. The outfit can be repaired using various "pre-War" and merc outfits including pre-War hats.

In the Pip-Boy, its effects are listed as "Naughty Nightspeech", and the G.E.C.K. has it named internally as 'Amorous Attire'.

Locations
It is located in the Marigold Station near Grayditch. Look for a door with a yellow turning light above it. It's inside an average-locked safe inside that room. There's also a key inside a fire hose box somewhere inside the station.

Unmarked quest: Grady's package
A humorous side quest (actually a sub-plot to the Nuka-Cola Challenge) involving the naughty nightwear can be found in Marigold Metro Station, which is near Grayditch. Two can be obtained by getting the first one out of the safe and dropping the item and talking to Lug-Nut who comes to you and then giving it to him even though you do not have the item in your inventory you can still give it to him after that simply kill him and loot the item.

Bugs

 * The naughty nightwear's world model is bugged; when dropped, it looks identical to the sexy sleepwear. The all-nighter nightwear, however, displays an accurate world model, leopard-skin and all. It also shows on the clothing "nightware".
 * When you are accosted by Lug-Nut, if you drop the nightwear before talking to him, he still thinks you have it. Furthermore, if you "give" it to him, he'll spawn his own 100% condition copy before running off. Killing him will net you two copies of the nightwear.
 * When handing in the naughty nightwear to Ronald in Girdershade, if you managed to exploit the Lug-Nut "drop" bug, you cannot hand in the quest with two instances of the naughty nightwear on you. Simply drop one and then talk to Ronald to complete the quest.
