My USA Kilt is a Casual with a 66 inch waist and 68.5 hip, when you measure your hips imagine a line dropping straight to the floor from the point on your gut that sticks out the most. Measure as if that point was where your hips actually are. As to hose, I just got 2 pair from the http://giftshop.scottishtartans.org/hose_lewis.htm the fully fashioned hose at the bottom of the page, my calves are 20 inches and these hose are so comfortable, you will be amazed! I will order more in the coming months.
