Reece, wear your shell jacket as you see fit my friend & dismiss what others may advise because when it comes down to it, you're the one that will answer the questions when they're asked. If others would like to have their opinions on how things should be worn then more power to them. When I'm involved in a parade or ceremony w/the SCV I wear what I wear to Honor my Heritage. Why does one wear a kilt made from their clan tartan? To Honor their Heritage!!! At least that's how I see it.
