I followed this guide from the kilt maker when I ordered my kilt:

Waist ___(the stomach at the navel which is the widest for men; narrowest for women. Where women wear their belts.)
Ledge of Hip Bone ___ (This is where men would wear a belt with a pair of pants)
Hips ___(The widest part around the seat)
Length ___(Taken from the ledge of hip bone to middle knee while standing straight; we add 2" to this measurement. Provide total lengths for below knee skirts, we will not add 2" to these type skirts.)
Trouser Inseam___
Your Height ___ (in feet and inches)
Total length of a kilt you currently own___

I don't have it yet - it's still being made.

I just noticed that one of the reasons that my current extreme budget kilt fits so poorly is that the hip circumference is pretty wide - the pleats splay out because the place they're sewn down doesn't fit me very tightly. I'm basically tube-shaped, with a 44" waist, hip ledge, and hips and those are the dimensions I gave to the kilt maker. My concern is that the new kilt will come out with the same poorly-fitting hip line.

Is this a valid concern?
