A leotard is a skin-tight one piece garment that covers the torso. The name is from the france acrobatic performer Jules Leotard. Leotards are worn by acrobats, gymnasts, (ballet-)dancers, figure skaters, athletes ... I made a more female version of it, normally this piece of cloth is considered unisex. It should be for a series of ballet clothes. Delete-groups are used, where no transparence is available. The material normally is nylon, so it is a bit shiny. So the exported version in Blender looks quite realistic. Nevertheless I connect the entry of the glossy shader to the texture in Blender.
