That's exactly the tux/hair combo I was picturing! Technically, though, wouldn't he have worn a morning suit? A tux is evening wear and the wedding was a morning affair.

Seems like most of the men were wearing morning suits. Yet another occasion when a man can just roll out of bed and get dressed while a woman has to plan her dress/hat/makeup. :p
Clark was wearing a morning suit when he married the clone (IIRC).
