Just to confuse you, remember there is a wing tip collar tux shirt. Normally has pleats, high, stiff collar where only the front 1 inch folds. It is designed to show off the bow tie. A true tux shirt only has button holes for studs. The more common have accomodations for both. The button arrangement is 1 at the bottom, inside pants never seen, 4 studs and button at the neck. The cuff can be either a standard cuff, as shown by you image, or a French cuff. The French cuff will require cufflinks. I have spent many an hour in these shirts.

I must remember to remember what it was I had to remember.
