Hail,

Ever since borrowing a kilt for a graduation party last week, I have been really despising my arbitrarily restrictive pants (even my handy cargo shorts) and have decided to convert to kilts *much rejoicing*. I've got a black Survival model Utilikilt on the way, and I'd like to get a more traditional wool kilt for more formal occasions. I'm currently in America, but I'll be moving to St Andrews, Scotland to go to the university this fall. I'd like to be a light packer in my forthcoming travels, so I'll likely be sticking with two kilts for the foreseeable future.
What I'd appreciate some help with are:
1. Belts: Is a belt necessary for a UK? If so, where can I get an inexpensive simple black one that will last me? Could I get a good belt now that I could use for either kilt?
2. For my traditional kilt, should I wait and shop in Scotland or order one?
3. I'm trying to decide between a simple gray and black tartan or a plain black kilt. If I get a black one, would it be ok to wear casually (when the UK is out for one reason or another)?

Apologies for the inundation, any advice for the soon-to-be-kilted would be greatly appreciated.
