Strange -- I'm having the opposite problem. My kilts are growing. I thought it might have something to do with losing 20 pounds while suffering from malaria, and then watching my diet and exercising because I was glad to have the weight off (the one good side effect of malaria).
But now I'm wondering if there isn't some universal constant waist size of kilts, and as some experience shrinkage, others simply must grow.
