If you're using 3.0, then you would add the animations to the FX layer. For instance, you'd make a layer called "Shirt" with weight 1, then drag a ShirtOn and ShirtOff anim into that layer, set ShirtOn as default state, transition from ShirtOn to ShirtOff when Shirt = false. Then you'd add an entry to your Expressions parameters and menu, variable Shirt boolean, and a toggle Shirt On with parameter Shirt.
