it gets longer with time

i have this disney cuties shirt...  the print says, 'is it a crime to be this cute?' (nyahaha...  toinks!!!)...  the tag says, 'Buy your exact size!'...  it's 90% cotton, 10% spandex... i've had it for more than 10 years...  it used to be just hip-length...  now it's already a little above the knee...  hmmm...  shirts 'grow' too, huh!  ; )
