I'm at work today and I have a undershirt on that keeps coming untucked. I hate it as much as I hate IU. What the world needs is a solution for men. What about a Men's onesy? If I buy the size I need they fit great until they get washed...the next size up swallows me, even after a wash. They need to make extra long undershirts. The only solution out there now is the underwear tuck, hiking your pants up or dealing with it. Very frustrated.
