1) 1.25 inches2) Modern and simple square / rectangular buckles3) Silver4) Black, navy, racing green. Maybe Oxblood. Equus makes nice belts but I wish they had more modern looking buckles in silver. Also I'm on the fence on how suited bridle leather is for formal work-wear.
Nice stuff. No clue why navy is the least popular but I'm happy because it was my first choice and the only one still left along with black.
To change the size I suppose we just email the generic Epaulet email id?
