The most flattering outfit for female characters in the game is the mechanic jumpsuit of all things.
@WhyNotZoidberg are we talking full work-safe coverage or ... ya'know, long shoulder straps...
@arichtman
A proper jumpsuit. But it is the only piece of clothing that gives women a nice butt (not seen in this picture). Everything else makes all butts look like well... mine; a 50 year old manbutt.
Which kind of is nice tho, FO4 have no sexualized clothes whatsoever.
