I'm thinking of having a mid- or dark-grey suit made up (not so dark as the British definition of charcoal) and I'm wondering what the right button color and material would be for such a suit. Is brown horn acceptable? What are the other good options? Secondly, how many cuff buttons would you put on the following jackets: 1. Navy linen unlined, 2 roll 3, patch pockets 2. Navy 14/15-oz fresco blazer, 2 roll 3, lined with besom/flap pockets 3. The suit described above In general I put 4 buttons on most jackets (suits and blazers/odd jackets) but sometimes do 3. I'm wondering if 2 buttons would be more appropriate on the linen and if 3 might be better on the fresco blazer.
