This is a one piece bikini. It is colored white and there is a node setup supplied, so that you can recolor it (e.g. like in "Baywatch"). There is also advice how to use the shrinkwrap modifier to make it skin-tight. A normal-map is also supplied. Delete-groups are used. Be aware to switch them off, when you will work with transparency. There are also two methods to simulate a wet swimsuit, one is simply to reduce roughness of the glossy node. There is also a second texture added, where transparency is used except where the seams and crotch-area are. This is more "sexy". Be aware that for a dark color you need less(!) transparency to make the skin visible. But decide yourself, which way you like ...
