Leather pants - Standard size leather pants. Maybe a little too big or tight but you can wear them with some discomfort and loss of mobility.
Leather pants (fits) - Oh man, these fit you perfectly. You can hardly feel them while you wear them!
Leather pants (large) - Oh jeez. You’re going to need two sessions with a sewing kit before they fit you perfectly. These are huge! Although in this current state, this item could accommodate mutated anatomy.
Leather pants (too small) - Nope, too small. Can’t quite wear these. BUT. You could “hack” these with a sewing kit. Cut the pants in half and adjoin the halves together with thread so that they fit you. Good as new.
So the steps would be:
Leather pants --> Leather pants (fits)
Leather pants (fits) --> (OK)
Leather pants (large) --> Leather pants --> Leather pants (fits)
Leather pants (too small) --> Leather pants (fits) …OR… Leather pants (hacked)
Then you could have:
Leather pants (hacked) - These used to be too small but then you found scissors or a similar cutting tool and some thread to adjoin the halves together. Now they fit you… but they don’t hold heat quite as well. Good for summers, bad for winters.
Maybe come up with a better word for ‘hacked’. And if we have ‘hacked’ clothing, should we be able to produce them from normal clothing, too?
Oh… right. If (large) clothing items could be worn by mutated characters, would that make them overpowering?
