It would help if your gun skill, perception, and sneak skills are of decent level.
Obtain a silenced .22 Pistol and some bullets for it, enter Gomorrah casino and turn over your weapons except your "hold out" weapons. Make your way down to "brimstone" in the area where there are a lot of prosttutes dancing. Once you enter find a vantage point where you can crouch with a clean shot, and not be seen, I find that area with the steps and two doorways is a good place. Kill them with a clean sneak shot, loot the body.
Or if you don't care about infamy you can just blast the girls on the strip, loot em and run out real quick. But if you sneak and kill the ones in the basemant of Gomorrah, you can kill enough of them without having to fight everyone so that you can repair these outfits to maximum condition.
And it seems these outfits take a real beating and last quite a while.
If anyone knows another way to get these outfits without killing the girls (or guys), please post it here.
