In our daily lives we find out old shirt don’t fit anymore or we outgrew those pants and they look ridiculous on us now. But what about costumes? I know some suit expand such as the ones made from unstable molecules but not everyone got the money for one of those, local heroes use regular suit which they fix themselves but guys like Iron Man live in a can or any other armor hero, if you got any bigger your going to feel like a sardine. 
 
Let say you outgrew your suit, you can’t walk down the store and get new one and if you order the materials for it people going to know what your making or have good idea and let say they don’t, then comes the part you got you make on your own. I sure don’t know how to even string two things together I done in the pass out desperation but that about all and broke down the moment put in the washer, it be lame if your costume rips half way through the fight.
