As a historical note, the high collar military jacket of this type is the direct forerunner of the standard suit or sport jacket. If you fold the collar of your suit up, the notch in the lapel is what separates the standing collar from the front of the jacket where the buttons are aligned. the button hole on the lapel is the top button of the old military jacket. The high collar is still being worn here and there in the more formal style of military uniform including the USMC's blues.
