The swimsuit has three different materials: swimsuit_02_cloth_1, swimsuit_02_cloth_2 and swimsuit_02_clip. You'll see in the illustration where each material belongs to. If you prefer the blue swimsuit you'll need the diffuse texture from http://www.makehumancommunity.org/content/f_swimsuit_02_blue.html. The golden swimsuit (swimsuit_02_cloth_1_gold, swimsuit_02_cloth_2_gold) works differently. It's mostly procedural and uses the textures from http://www.makehumancommunity.org/content/f_swimsuit_02_texture_creation_kit.html as masks. Textures are NOT included in this zip file.
