In 55 years of wearing kilts, every one I have owned has been tailored for me in at least 16oz wool worsted material. I have had MacKenzie, Anderson Modern, Anderson Ancient, Anderson (MacNaughtons of Pitlochry), Anderson of Kinneddar x 2 (LochCarron Weavers) and MacLachlan Modern. It is well worth the expense to make certain that a kilt is fit and suitable for all you would want from it - and although the cost is perhaps a little extra, you will have a robust garment that will last at least twice as long as even a 13oz material. For a kilt to fit properly and feel right, it has to be tailored. We wouldn't be posting in this forum if we didn't appreciate the better aspects of kilt wearing and in that respect, casual kilts (as they call them) just don't cut it!! - PipingScot.
