I have this in the form of two blazersuits, one for warm and one for cold. Both jackets have brown buttons, which I find limits them to the day time as brown buttons and black shoes just rankles. I recently took delivery of a new blue odd jacket in linen, with blueish MOP buttons, which allow the coat to get some use in the evenings if need be, while still being different enough to avoid the jacket looking like an orphan.
Now bearing in mind that unfortunately I simply can't handle brass/gold buttons, is there some type of button which will offer similar flexibility for a winter version (when MOP is out of place obviously)? Would normal blue buttons risk the orphan look? Am I overthinking the whole thing?
I remember a post on ASW (though I can't find it now) about blue blazers with black buttons - I like the idea, but I guess that would have the opposite problem.
