There is a VERY specific way to measure your waist to determine your size.  Check Youtube.com for directions since it is NOT your pants size!!!  I purchased one directly from SportKilts and am very happy with it.  It is a bit small but the velcro holds it just fine and I also bought a belt for it.  The tartan is very important to clans but if you just want something that looks good and doesn't cost an arm and leg, this is a good kilt.
