Do your animations just toggle the Parent Object of the outfit? If that's the case, you just need to make animations and parameters to turn on/off each individual part of the outfit that you would like to be able to toggle, then add them to your animator. For instance, if I had an animation that toggled ON outfit "Daily" I would then create toggles for the clothes items individually like jacket or socks in their own on and off animations. OR, you could use something like Modular Avatar, where you don't need to edit the FX layer, add parameters, or make animations at all and just use their MA Menu Item Component and MA Object Toggle Component. You may refer to my comment here for some information on setting up Object Toggle Components.
