I had a roommate back in college (early 1960s) who wore his calfskin opera pumps with jeans. He was from old money and didn't give a crap about what the other guys thought. He was from old money and the girls didn't seem to mind a bit.

I would never wear them but........ http://barimavox.blogspot.ie/2010/08/black-tie-decolletage.html
Before I was married I had a group of single female friends who used me as their +1 to charity gigs, etc because they knew I knew which fork to use and they wouldn't have to fight me off at the end of the night.
Went through a couple tuxedos and a single pair of Bally calf opera pumps that wore like iron and felt like buttah!!
I like the way they look and the chances are/were that, even at a so-called formal event I'd be the only guy there wearing them.
The only other men were usually older...MUCH older.
