you could tie it. just bunch the back up into a tail and put a ponytail fastener around it.
tuck it in
Easy get it kinda big and tuck it in ur pants pull.it out some so it is airy akd light than take a nice belt and wrapit in the middle
You can belt it and wear it with tights. OR you could roll it and tuck it to fit you.
rip the front a lil bit and tie up the part around your waist.
Pull the extra fabric in the bottom and tie it with a hair tie, then you can party like it's 1996! :D
Or you could buy a girl's shirt, if you have a way to get to a store. It's almost winter, right? That gives you a reason to carry around a jacket to hide clothes inside, after you buy them. It would keep them out of view of parents and such.<br />
And trust me, no random shopper is going to give you a weird look for buying a girl's shirt. There are dozens of other reasons why you might be buying it, other than to wear it yourself.
unless it's a small shirt..you can't. the only thing you can do is it accentuate the girl within that shirt.
maybe shrink it in the dryer?
