Lacy underwear is a quest item obtainable only in Tranquility Lane in Fallout 3. It belongs to Martha Simpson.


It can be found in the Simpson residence on her bed. It can be used during "Break up the Rockwells" in Tranquility Lane. Place it on the Rockwell's workbench in their basement and tell Mrs. Rockwell that there is something she should see. She will follow the player character to the basement, where she can be convinced that Mr. Rockwell is either cheating on her or a cross-dresser.
