Actually Blu, I believe that one is the "MacLeod Of Lewis" tartan.

The only "Dress" MacLeod I've ever seen is the "MacLeod Winifred Mary dress" tartan; MUCH less eye watering :

My clan (MacCorkhill) is a sept of both the MacLeods (of Lewis) and Gunns, so you may guess why I'm leaning toward the "Gunn Modern" tartan for my next kilt!
