I found a number of kilts on Amazon that are within my price range but when I started looking closely at them I discovered that I have no idea what a lot of the references mean in regard to what size kilt I should purchase.
What does a 3-yard kilt indicate versus a 5-yard kilt?
I understand that 10 ounces versus 13 ounces indicate the weight of the fabric, but in practical application what does that really indicate and how does it apply to everyday wear?
How does it apply to formal versus casual wear?
I'm 6'2, around 210 pounds with long legs and a short torso, but my legs, my hamstrings, quads and glutes are fairly large do to heavy weightlifting, so how do I determine what length kilt I should buy? I've seen references to 22 inch kilts and 24 inch kilts.
Should my kilt hang below or above my knee?

I know I just ask a lot of questions but I want to make sure that I do not look silly or wear the garment improperly when I purchased my first kilt.
