I posted this in one of the waiting room threads, but I think it does a good job of showing that with a good holster and a belt that keeps your gun snugged up against you, you don't need to wear clown-sized shirts to keep your gun covered. With a t-shirt you just have to be careful of bending over forwards to far because the fabric is kind of thin and the grip will print a bit.
Everyone recommends wearing extra long shirts, but if your gun is showing then your stomach would be showing. I can't remember the last time I was out in public and walking around with my belly hanging out, but maybe it happens.
