Rob,

I did get your Tartan fabric request and will be replying via email. I am a member of the Scottish Tartans Authority and have commercial accounts will almost all the major weaving mills.

Your Tartan is readily available.

There are some kilt makers out there who offer a couple of different options for Side Slash Pockets. Most are like Utilikilts and your 511 who offer pockets on solid colored kilts only.
Those who do offer pockets on Tartan Kilts are mostly like SportKilts.

If you want a truly traditional looking Tartan Kilt with pockets I'm afraid I'm the one you need to see. I was the first person, and as far as I know the only person, to figure out how to put Side Slash Pockets in a Kilt and have it retain the look of a full traditional kilt and also have the pocket not disturb the hang and swish of the pleats.

As an example here is my Dress Blue Tartan Kilt.



If you look closely you can just see the left side pocket below my left elbow.

Here is a shot with my hand in that pocket.




The majority of my kilts are machine sewn. They still retain the full stabilizer and interfacing of a traditional kilt it is just moved and modified to accommodate the pocket placement.

My Dress Blue Tartan Kilt is fully hand-sewn in accordance with The Art of Kiltmaking.

I'm an Engineer and my pet peeve is bulging pockets. I am trying to find the photo essay I did a few years ago where I pull all the stuff I keep in my pockets and lay it out on a table. I love doing this and love watching the faces of people who cannot tell that there is anything in my pockets even when loaded with a keyring, my pipe, lighter, pipetool, change purse, hankie, and sometimes even a flask.
If I can find that photo I'll post it.
