rtc872,

I think there may be a little confusion in terms here.
If by Traditional you mean a full 8 yard, hand stitched, Wool Tartan Fabric, Kilt with full interfacings and stabilizers, made in the traditional style -
As far as I know there is no one currently producing such a Kilt that includes pockets as a regular part of the design. (There may be, I have just never heard of one.)

But, if you are referring to a full 8 yard, Wool or P/V Tartan Fabric kilt that rivals the look, hang, and swish of a Traditional, then there is only one maker that I know of.

Here is an 8.36 yard, 16oz fabric, X marks Tartan Kilt.


here is a pleat shot of the same kilt.


And viola, here are the side slash Pockets


And the Under-Apron Pocket


As an engineer I take pride in the pockets in my kilts. I cannot find it right now but somewhere on the forum is a set of pictures of me doing one of my favorite tricks. I stand in front of someone and ask them if they can tell if I have anything in my pockets. When they say no, I proceed to pull out my pipe, lighter, pipe tool, car keys, cell phone, tobacco pouch, and change purse. In all it is difficult to hold it all in my two outstretched hands. But I can have it all in my pockets with no bulge or distortion of the look of the kilt.

If you see almost any picture of me in a Tartan Kilt that is exactly what is in the pockets.

I then take my cell phone and slide it into the Under-Apron Pocket and tell them, "It's on vibrate, call me, please.". I have never felt my blackberry in the pocket. It hangs just right where it does not flap or bounce. And in the car I can reach my phone without it being caught under the seatbelt.
