The Bear kilts are a bit different. I have always worn a belt with my bear kilts. With the velcro closures, there is no way to get a really good cinch so the kilt doesn't slide at least a little even with a properly fitting belt. In 3 years of wearing my 3 (oops I only have 2 now...) bear kilts, I have never been able to go without a belt.

A traditional kilt is a whole other creature. I have yet to wear a belt with my trad (I sold the belt in fact) as It has never moved on me. As Steve pointed out, the top strap tightens at the natural waist. So even if your seat meausrement is 1 inch bigger, the waist will not fall down. I should point out that I have heard that with a traditional, you cinch the waist as tight as is comfortable, but you don not do the same with the second strap on the hip, which should be a bit looser.
