The central portion of my torso isn't exactly spherical or cylindrical, but even being a bit overweight, it is nowhere near 52.8 in, circumference. (My waist size in 38 in., and my hips measure 43 in. I am a male, 5ft-11in, 190 lb.)
And your body at your waist or hips is probably at least three times as wide as it is deep.
If we assume that exact ratio we can model the cross-section of your hips as a rectangle of width 3x and depth 1x, with a total perimeter of 8x. If we shove in the figure for your hips we get 43" / 8x = means x = 5.375. Width is 3x so 5.375 x 3 = 16.125". Congratulations, you fit.
