About to do an emergency run to get dress pants! Thanks to everyone that respond.
I have proper dress shirts, and a sports coat, but have in the past been wearing them with (nice) jeans - and the pants from my wedding, of course, no longer fit.
One snag is that I normally need to have the legs shortened, but eh, will just have to pay for rush alteration.
(You can tell I work in a field where dressing up is not required)
