I should say right off the bat that I am a huge fan of Stillwater and own 5 Stillwater kilts, including 2 economy kilts. On the last economy I got (Irish National Tartan closeout), however, one of the straps started disintegrating after one wash. It's almost in two pieces now.

I have not bought from Kiltmart, but read a review that said there were some problems with the straps on those too (detaching from the kilt I believe).

You get what you pay for.

I do still love Stillwater, and my solid black economy kilt has made it through several washes unharmed.
