While I would NEVER do so myself, I have been to a couple of local weddings recently where some of the guests were in less-than-casual attire. (Shorts, tank tops and flip-flops for the young 'ladies'; droopy casual pants, tank tops and sneakers for the young men - more or less what they wear every day. Most of the older adults were more appropriately dressed in suits and skirts/dresses.)

There goes the idea of Southern gentility and wearing what's appropriate. Sorry Sandford. (I consider Louisville, KY as being a Southern city, even though we're on the extreme northern edge of what's considered "The South", although it's not the "Deep South").

Even at the wedding of one of my late uncles, there were some men who showed up in just their shirtsleeves (and this was back in the early '80's, when people were still a little more formal than today).

The last wedding I attended, I spoke to a couple of family members to get a feel for what was expected. I knew the couple wanted something kinda dressy and formal, so I wanted to know if my PC & kilt were OK, would they prefer a tux, or should I go more casual? I wouldn't have attended in anything less than a suit (it was an early evening wedding with reception following immediately). I wound up wearing my PC & kilt. Sorry, I don't have any pictures of me, but I'll see if I can get some soon.
