Also buy plain white undershirts.

I can't stress this enough.

It extends the life of your "dress" shirts and you have to spend less on replacing, it eliminates pit stains and you don't have to worry about someone seeing your chest hair matted under your shirt

Undershirts are so key, make sure they are long enough to stay tucked in, otherwise they will untuck, but your shirt will stay tucked and you will look fat and dumb.
