From SWK Size info;




Our Economy, Standard & Heavyweight kilts are offered in EVEN waist sizes 30"- 52" (subject to available stock). Size is determined on our kilts with the buckles fastened at their tightest position. This means a 34" will go up to about 35.5". Kilts look & fit best with buckles at the tighter positions for maximum overlap. This does not mean the kilt should be tight when you wear it! If you are not sure about size, keep in mind that it is easy to alter a big kilt to make it a little smaller (just re-position straps & buckles) and very difficult to alter a small kilt to fit a bigger size.

Basically, order whatever size your measurement comes closest to.






Also remember to measure with the kind of shirts you will wear. I measure 41 and I got a 40 because I thought I would lose weight and depending on the time of the year I wear the kilt on the tightest hole but in the winter when I wear two layers of clothing I some times have to wear it on the last hole.
