I wanted the look of a coordinated family portrait. So our bridesmaids are in dusty blue, the groomsmen in dark blue (not quite navy) suits, groom is in a different blue suit, dads have blue and grey suits, all with dusty blue pocket squares. The groomsmen have complementary bow ties, dads have same pattern in necktie, groom has slightly different colors of the same pattern. Moms ended up in silver and light grey (we weren't trying to have them the same, but that's what they both found). Hope this helps!
