I can't fit into my army uniform!

just curious about how much growth my biceps have been after i left for australia, i took out my army no. 4 uniform to test it out. you know we have to fold up the sleeves, and it's taught that we should fold up 3 folds, my arms can't even fit with 2 folds! omg.. should i be happy, or should i feel sian that i may have to get a new set of uniform? haha! i shall strive to be the fittest clerk in OCS when i resume my NS.. hoot!
