Welcome to the forum. Enjoy! Belts . . . first you need to get used to the idea that a properly fitting kilt does not need a belt to stay up. It is quite a surprise the first time you strap on a good kilt. Then, it is up to you whether to wear belt or not, as the belt is not functional, but for looks. Personally, no belt with a sweater or waistcoat. Belt with just a shirt or t-shirt.
