If the game want to continuing for the next 10 years, they should utilize Dream Fitting for wider function. It should be a collectable menu where you can retrieve any glamours that you have check-listed or try on unobtained ones.
It should be 100% doable even with the spaghetti code (it really doesn't sounds complicated when we already have market board you can "obtain" items anytime).

Can keep the glamour dresser for those want to keep the attributes attached to particular glam (dyes/signature/etc).
