FWIW my suit is a navy (poor pic ). Navy suit, dk blue tie, white shirt, white square, dk blue socks and black oxfords. The departed was an academic/engineer, and most of his colleagues, friends and other loved ones at the funeral were wearing sombre tweeds and odd jackets. Engineers aren't known for their snappy dress sense AFAIK. Only the sons of the departed wore black suits, so this funeral pretty much conformed to Eliod's comment.
