This is a rather interesting piece of cloth. It is 10% transparent, so no delete-groups are used. The shirt is designed to fit to the tight jeans and the strapless bra. You may change the small rings to a shiny material in Blender. In Makehuman, the leather litsphere is used to make the normal-map visible.
