My first (and currently only) kilt is a black AK. I have no problem. Yes I get some strange looks, people trying to figure out what it is, but that only makes a difference if you let it.

Be comfortable and confident in whatever you wear and others will see it and respect you and the Kilt!

Traditional tartans DO receive an immediate recognition as a "Kilt", so if there is any hesitance, get a SW, USAK, or Bear (though Bear is a little backed up it seems right now), and wear it!
