I'm not sure about attire in any detail, but it will be casual...pretty similar to the OP's pic, except I'll be wearing a flatcap.

As for plans, my wife is going to an art educators convention in Seattle and I was going to tag along so I could visit home for a few days, but due to unforseen emergency expenses my plan fell through, but, since her school is paying for her to go she's still going. On the other hand, I get six days with no wifely supervision!

Since her flight leaves on the 16th, I'll be spending the 16th, 17th and part of the 18th in Rapid City, SD with my Brother-From-Another-Mother, hanging out wherever we find something fun. Also, he's never worn a kilt, and I have one that should fit him nicely. Hopefully, we have decent weather this year!! Last year I spent half the day digging out of the house--which is what I'm doing today.
