This is probably going to be an unpopular opinion, but I think having fewer glamour plates would be better.

Having too many glam plates cheaper them and removes the incentive to really make good glams. With fewer plates you'd have to really make choices about which outfits to keep and which to throw away, encouraging you to put more thought into them.

For example perhaps you'd think twice before allocating one of your precious few plates to a basic draped dalmascan top outfit, or to a joke frog head outfit. You would instead have fewer, better outfits.

Less is more.
