Fitting a High Hip vs. Sway Back

Threads #85, Oct/Nov 1999

Fabric rolls up on my skirts and pants just below the waistband across the back. I was told this means I have a swayback, but I altered for the swayback, and the fabric still rolls up. What’s going on?

A high-hip curve and sway back are commonly confused figure variations, says fitting expert Judith Rasband, because they can exhibit similar symptoms, particularly the one you mention: excess fabric at the back waist. I suspect that you’re dealing with a high-hip curve because you say that your fitting problem is the same on pants and skirts; whereas, a swayback causes different problems on pants and skirts.

In reality, the full hip circumference may be as little as 1 in. or as much as 10 in. below the waist. A high-hip curve is generally positioned within 2 to 4 in. below the waist, with obvious weight deposited just in the back of where a garment side seam would be. A high-hip curve often comes in combination with a large abdomen and a flat bottom. A low-hip curve is generally positioned 8 to 10 in. below the waist, with obvious weight deposited just opposite crotch level on the side thighs, where a garment side seam would lie, and slightly behind. Some figure types feature a combination of high- and low-hip curves, sometimes smoothly curved between, sometimes with a slight indentation between the two curves. Each of these variations can coexist with a swayback.
