Having a model with just the one outfit it's wearing means you can delete everything under it and have everything on one mesh and limited materials. Having a tonne of toggle outfit on one model means it'll always have two meshes (except nude). If you just make it go transparent then it's extra mats. Think in what is being displayed at any one time for optimisation. 100% transparent is still rendered. Everything else is just adding to file size.
