There are two things to consider:
1). the material being used
2). the kiltmaker and company

The tweed is a GREAT way to go! Very "Prince Charles-ish". When you look at the weight of the material, it will be sturdy enough to maintain a traditional sew-up, and thick enough to hold its form. The material itself will serve you well for quite a long time... with careful maintenance. Unlike some of the real thin crud that's going around, this material will take a beating and still look great.

As for the company, they are wonderful. I could not imagine anything but a top-notch kilt coming out of them. Experience speaks for this point.

All in all, I would have absolutely NO reservations in purchasing one!
