may be u could try washing it.. lol no idea.
But i have a few era caps. yea the size may be a problem.
But how come ur head can grow so big one?
hahaha. no offence.
probably try finding on ebay? for a bigger size, sell this one off.
New era made of cloth.. should be able to stretch abit further. but depends on how much u wanna stretch. if its quite alot then forget it la. just sell and try to find a new one.
When a a door closes, another will open!
May be ull find another more lovable era cap!
or like what others say. come a matrep and just place it on ur head. lol.
