There is nothing wrong with wearing a white t-shirt (sleeved or sleeveless) under another shirt, that's normal underwear. The problem is when you're wearing just your underwear in a social setting that does not call for it. Same thing with how boxer shorts cover everything that should be covered in an office, but it's not socially acceptable to wear just boxer shorts to work. You should have pants over top of them.
