Well, at first Martha just used it only for the Superman suit and not for anything else.
Then the capes began to wear out because they were further from his aura and closer to whatever form of damage he was battling.
Then as time wore on, his uniform began to fail. First the tights went --- because they were tight.
Martha switched to a 2 piece suit because she had to make an entire new one piece suit when the tights failed.
So now Superman had a re-design with a 2 piece suit.
Then finally the shoulders of the top failed due to the stress of the cape, so Martha had to make a harness that went under the top to support the cape.
Then the red boots failed, so Martha made cloth boots with soft soles so Superman could stash them easily with his uniform.
Martha was frugal so she had purchased the minimum of 2 full Superman outfits. So she had to go buy more material.
A new brand of spandex, stronger and sturdier came out, so she bought that and used it.
So I posit that she really didn't have extra cloth.
Cute question!
