Today's tuxedo pant sports a straight leg and plenty of "sit down" room through the hips.  If your current pair has a tapered leg or is tight through the quads or backside, you need to treat yourself to some new duds.

It's that strip of satin on the outside that makes it official.  Every formal event from weddings to prom, Quinceanera to cruising means you will be wearing tuxedo pants with your tux jacket, vest and tie.
