In imperial measurements, the perfect statistics are 36-24-36 for a beauty queen. That's 91-61-91 in metric terms. Together with a height of 5'9" (1,75m), you have the perfect body. The bust and hip measurements should be equal, and the waist measurement should be two-thirds the measurement. Oh, did I mention that if you can't fill a C-cup without padding, you need "chicken fillets" implanted.
Alas! That was then, this is now. The judges are now impressed by an imposing tall, boobless, hippy look that might be perfect for showing off high fashion, but is just so imperfect statistically speaking.
