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.

Okay... That seems to incline me toward the 40" then.

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.

Can you be a little more specific? What *is* involved? (no need to contrast with conventional tanks)...

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!

So, the net difference from each location is only about 1" and doesn't necessarily require any specialized knowledge to accomplish provided you can use a seam-ripper and sew-by-hand (that's reassuring).

Now... Does the outer apron have 1 or 2 buckles on Heavyweight SWKs? If there are 2, perhaps I might just omit reattaching it (unless the original stitching has marred the material underneath) if I'm going to the trouble of removing it?
