The last "off the rack" kilt I purchased was a Black Watch kilt from Things Celtic in Austin, TX. I am not sure who their economy kilt supplier is at the moment, but for around $110.00 I purchased 8-yard PV kilt with enough knife pleats in the back to make folks notice. The buckle closures are solid and the drape is quite nice as well.

Other than that, I have a Royal Stewart Sportkilt which I use from marching. I live in Texas so comfort is a big issue. If the fit is fairly good, then I have no problem wearing "off the rack".
