I wear my dark grey tweed Argyle for funerals. I also wear a bronze coloured buckle on my belt which is no so "in your face" as the shiny silver ones. I wear a black or sometimes white shirt, black tie and black hose. I normally get a "thank you" and or "nice to see someone making an effort". I feel that the Argyle with silver buttons is a bit too dressy for that sort of occasion. Unfortunately I am having to wear this more and more nowadays.
