I have never seen a problem with it. I know alot of guys that tuck in their t-shirts and nobody has ever said anything about it or verbally asked somebody why they tuck their shirt tail in and how weird they thought that was. Its really nobody's business on how somebody dresses. There are more important things in life like bills to pay and jobs to hold down instead of worrying about weather a mans shirt tail is on the inside of his pants or not. It is so stupid. That is a personal preference. There are a few that think it is weird but most don't think nothing out of it or even give it a thought. I never could understand why simply tucking in your t-shirt makes you uncool when it doesn't. We all know people in our lives that tuck in, people close to us and we don't think anything about it, and they are not any less cool than those who don't. That alone doesn't make a man weird at all. People just need to quit worrying about dumb things like that. Its all up to the person themselves and how they wear it. Some of the coolest people tuck in their shirts. We shouldn't judge other people just cause they prefer to wear their shirt tucked in. There are weird people who don't even do it.
