This part of the Bikini should be combined with the Bikini-02 (slip). It will not fit on extrem cup-sizes and also looks weird, when you put it on kids ... Delete-groups are used. As a material I tried a combination of normal-map and diffuse-texture which works in MH itself. So I took the leather litsphere. When you export it to blender the litsphere does not matter, because the materials and textures are added as always.
