Sporran strap issue

[Cowher]

I am a gentleman of substance. So I have some issues with my sporran belt/chain.
(1) when I sit the sporran sits on my lap leaving slack for the strap to slip lower and then once I stand my sporran is much lower than desired and needs to be readjusted.

(2) the sporran slips down to where the strap is pulling the kilt under my gut. Thus making my belly look HUGE!

I don't have belt loops on my current kilt so using belt loops to hold the sporran up isn't a option. I also HATE sporran hangers. For what ever reason I just don't like the look.

Does anyone else have this issue? What do you do? I
Am currently designing a solution but wanted to see if I am over thinking things.
