There is no hottest chick. You have to take into account personal preferences like height, age, breast and ass size,. race , hair color, weight ...even just looking at a photo.
Take the last 10 Playboy playmates, I haven' t seen them....but I'm sure they would split the vote pretty evenly, not like one gets 25% of the vote and another gets 4%.
Most here would basically agree if a woman was hot or ugly,, but the difference between a 9 and a 10 is in the eye of the beholder.
You can never say hottest ever, it is too subjective.
You can say tallest, say a 7' 5" woman might be the tallest living woman,that can be measured.
