She had the default dress she uses when dating her on the fancy restaurant. I haven't given her any clothes.
Yeah i duuno these few past updates devs seems to like to undress girls as well as MC in random places. The other one i find odd is when you spank girls in the office MC is naked in that scene too.
The one i keep getting is that whenever Mike spanks a girl on the nightclub, a red mark appears on his suit.
