You can't go wrong with a custom made from USA Kilts. For the little difference in cost the difference in fit and quality is worth it. If you are concerned about measuring properly one of the benefits of dealing with a kilt MAKER as opposed to a Kilt reseller is that you can speak directly with the person making your kilts. Rocky is well known for his quality kilts as well as for his customer service. If it is just the casual model you are looking for, I believe they do have some off the rack models as well.

Personally I would give Rocky and call and see what he has in stock before I even considered an acrylic. I have owned acrylic and I have owned Polyviscose and for casual wear nothing beats the PV carried by USA kilts. Machine washable, teflon coated, comfortable as can be, and it has a better look and hang than the acrylic in my opinion.

Welcome to the forum by the way.
