Last year, someone on the Yahoo site (I think it was Ron?) suggested using snap extenders to "adjust" the size of Utilikilts. I was a little doubtful, but a lot of guys thought it was a good idea. I found these for $2/ea. while I was going through the BudK catalog and thought I'd pass it along.

I'm still doubtfull; you'd have to have some subtantial adjustments to make in order to use them, and I'm not sure it would look good, but if it works...
