I have a MacMillan Black from UT Kilts (I'm wearing it in my avatar) and I have a MacNaughton from Atlanta Kilts. They are both presentable and suitable casual kilts. The Atlanta kilt definitely has more heft to it and I think it's built better (however, I think my casual Kilts from Scotweb and USAK are superior). IME, my UT Kilt has had more of an issue with wrinkles than the Atlanta one.

You might want to order a swatch of the acrylic tartan from Atlanta if you want to get a good feel for the material.
