How to prevent a kilt from dropping

[meinfs]

Pardon me for being blunt friend, but the best solution would be to lose some weight.

I know it isn't easy, but you'll look better, and you'll feel better. Once you have a waistline, your kilt will stay up just fine.

Cheers,
Rick

Alrighty then.... While I do not have an issue with weight, and you may not, my friend does and he has earnestly made efforts to lose weight. Alas, it is the easiest thing to say but one of the hardest to do. It is a solution that is also rather obvious to most, and it can be done, as "Jared" on TV has.
But in the meantime, the immediate issue at hand is how to prevent a kilt from dropping like it's hot.
