It just occurred to me that I am supposed to go to Mesa, AZ in a few weeks (mid June) to a convention and I think I am covered for day wear but the last evening is a banquet of sorts with awards and dancing.
It's not formal - think dressed up cocktail party not formal gowns - but it is Arizona so my typical Bay Area choices (i.e; black) may not be right. Then again, the entire event is in a hotel with AC so not sure how uncovered I would want to go.

At last convention with same group I wore wide leg black pants, satin tux blazer and cobalt blue tank with silver sandals, fun jewelry and felt great. You kind of get all sorts of outfits.

Any ideas - I will start rooting around closet tomorrow but shopping for trip on Sunday (mostly for my mom - she;s going with) so I can hunt then.
