There are many different styles of t shirts out there. Some people really seem to like the style of long body t shirts. They are able to cover a little bit more of the torso area, and they can also be a little bit slimming.
One thing we keep in mind is to find just the right outfit to wear this with. Many people will go with long pants, because it will make the entire body look a little bit skinnier. This is a good look for someone who might feel like they are carrying a little bit more weight than they should.
If they are worn with shorts, the shorts can look a little bit weird at times. That is why most people will try to stay away from that if at all possible to avoid an awkward type of look.
