I am buying clothes and am wondering what is the difference between 2 button and 3 button. I know 3 button suits are more common today and 2 button suits are making a comeback. I just want to know how these suits highlight the body. For example, does one suit flatter taller profiles or heavier bodies? Does it matter what color (dark vs khaki color) I am 5 '10, 155lbs athletic lean guy. any input?
