ET@215 = Good Taste. @218 is a little sketchy. BD with DB and DB with no tie are both problematic. The former is really an “error” unless Astaire does it. Though if you are going to do it, do it with linen. It also helps that the coat is 4x2 rather than 6. Blue DB with white square really draws screaming attention to the lack of a tie. I think, if you want to do this, much better with SB.
Thanks for the thoughts. I suspect many of you will find fault over the coming weeks given my almost total reliance on the white linen square.
