Here is a great source for you bow tie seekers. They are not cheap, but there is a nice clearance section, with ties as cheap as $20 when you buy three. Be sure to see the one with the leaves on it

They also have ties and accessories made in the Carolina Tartan, to wear with your Carolina Tartan kilt or otherwise...
