First things first! Welcome,from a snowy Inverness-shire.

I can only speak about the traditional kilt.I have never seen any other at first hand.The top of the kilt may be a couple of inches above the belly button so with a belt on, the bottom of your belt would be around and about your belly button, a hands width below the bottom edge of your belt is about right for the top of your sporran.Might I suggest,as others have done,that you change your sporran chain for a leather stap.It will be kinder to your kilt that way.Have fun with your kilt.
