Hello everyone!

I recently found two tweed jackets that I am converting to kilt cuts to wear with my Black Watch kilt. Here is where the question comes in, I am looking for a vest or waistcoat to wear with my jackets to dress them up a bit. Forgive my ignorance, but growing up in the South Eastern states, I've had limited exposure to formal dress. What exactly is the difference between a vest and a waistcoat? And can anyone provide a source to purchase one that will not cost a arm and a leg. And finally, what colors would look good with my Black Watch kilt?


Thanks!
Seth
