I'm between sizes, too; I usually measure about a 33. I have both a 32 and 34 in the SWK heavyweight. I can wear the 32, but the apron feels just a little narrow. The next one, I ordered the 34 and moved the strap/buckle to allow about an inch smaller. This is very satisfactory.

One caveat is that the SWK's generally have the buckle tabs sewn into the pleats, rather than sitting "on top." So moving the right-hand buckle is slightly more involved than it might be on a traditional kilt. The corresponding alteration on the left side is to move the strap (on the under-apron) away from the edge of the apron by the same amount as the RH buckle. You should be able to do all this in an evening, but it helps to have a copy of The Art of Kiltmaking for technical guidance. I did not have the book on my first try, and that worked, too!
