Think of it like this: a bust to waist ratio of 35:22 is 1.6, vs. the average ratio which was 33:24.5 or 1.35.
That's a 20% variance in the ratio which, to a normal male observer is . . . eye-catching.
Interestingly that's ( 35/22) very close to the Golden Ratio ( 1.6180...) hence very appealing to the human eye !
