Not from any photos I've seen on this website. And I presume a tie in a regimental stripe would be in colors that match the regimental tartan. A regimental stripe tie is very different from what Electrickilt is wearing. Electrickilt is wearing a very common, garden-variety vest, tie, and dress shirt but IMHO they are not in the patterns, colors, or fabrics that you would "traditionally" wear with a kilt.
