Tuxedos
JB will be buying his tux. I think renting a tux is gross. Why would I want my future husband to get married in pants worn by other people? Eewww! Honestly, if he's old enough to get married, he's old enough to own a tux!
That said, JB's interested in the classic two-button tux. No pinstripes, no weird collars... His vest and tie would be white and the groomsmen might go sans vest or wear vests in a color that coordinates with my brideswomen.
Also, he's decidedly pro-pocket square. Boutonnieres get squished really easily and he's going to be hugging people all day. It's sort of a waste of $20.
These pictures are the sort of look he's going for.
