Alan... two things:

1). You WON'T find anything about the "Oakleigh" tartan from any of the registers, so don't bother waisting time looking, and

2). You CAN afford a handsewn (no machine stitching) kilt in a fine, soft wool. You can try the Highland Heritage store along with any number of Formal Rental shops in your area. It only takes a call to see what they have, and get them to sell you one in your size and a nice tartan for the same price as a... well... another kind of kilt.
