How To Tell If You Have A Perfect Butt

Is your butt perfect? If you are unsure, there is now a mathmatical formula, developed by British researchers, to help you confirm.

"The perfect female derriere has firmness to the touch and a resilience that prevents undue wobble or bounce, yet looks soft with flawless skin," Dr. David Holmes, a psychology lecturer at Manchester Metropolitan University, told The New York Post.

Here is the formula: (S+C) x (B+F) / (T-V)

Or try this way:

(Shape + Circularity) x (Bounciness + Firmness) / (Texture - Vertical Ratio Symmetry).

First, you have to assess the assets. Use a scale of 1 to 20 with

1 being the worst and 20 the best in the following categories described by Holmes:

• S = overall shape (a ripe peach being just about right)

• C = circularity (rounder is better)

• B = bounciness (less wobble is preferred)

• F = firmness (too much push to that cushion loses points)

• T = skin texture (no cellulite)

• V = Calculate the ratio of your waist to your hips.

How to do this: Use a measuring tape to get your waist and hip measurements. Measure your hip circumference at it's widest part, and measure your waist circumference at the belly button or just above it. Use your calculator and divide the waist circumference by the hip circumference or use an online waist-to-hip ratio calculator to run the numbers. Then do the math, putting your numbers in place of the letters in the formula above.  A perfect score is 80.
