Heya,

I am 6' 0" with a 31" waist, and have a great kilt that is 60" in width. When I put it on and place the ends over my shoulder, it tends to leave a ton of material on both ends, far more than a foot, and enough that I've been able to tie them together without the use of a brooch.

My guess is that a great kilt with 54" width would fit.
