Do the summer clothes have any effect? Like doesn't stripping the girls have the same outcome or do they give some kind of bonus money?

Summer clothes have one edge being that the neutral temperature would be supported as well as a +1 hot one (aside for the purely visual thing). Stripping only set the new standard 1 degree higher: a stripped girl in a normal Temperature will be cold but a girl with hot clothes will not. Indeed it's still still less powerful than the winter clothes hence the cheaper cost.
