Ah, but a true
dandy wouldn't want to call attention to his clothes
So true. IMO, the goal of this forum and why certain men flock to it, is to find refuge from today's uber-brand conscious society . While we do long for Edward Green shoes, Borelli shirts, Oxxford suits, and similar branded luxury goods, we do so not for the brand cache, but the brand quality. This philosophy plainly put: we dress for ourselves not for others. If you brazenly unbutton your jacket sleeves essentially you are accepting a self-conscious stance that you need to be defined by others -- "Please, someone notice my working sleeve buttons." The true dandy would never need such affirmation and would be self-confident in anything he wears. The only times I can possibly think of where it is OK to unbutton your jacket sleeves would be if: 1.) it's cold outside and you have to leave your jacket on to deliver a baby, and 2.) out of sheer irony: but in this case you should also be wearing a black suit with light brown shoes with a black belt and a short sleeve button-down shirt with a tie.
