First

Now I want to have the kilt adjustable, as I plan on going from a 43" belly line, to a 36" and I need some help (with pics please) as to how I go about this.

I was interested in how kiltthis.com does a kilt that can resize, and if there were other ways to do it that I am unaware.
Second
I want to have removable pockets and if possible a molle system, I would like to know how I go about this, as well as any tips, patterns, ect. That anyone would feel comfortable providing to me, either through pms of forum posts.
