According to a new poll by QVC . . . the shopping channel . . . women reach the peak of their beauty when they're 31 years old.

The poll surveyed 2,000 men and women, and here's some of what they found . . .

70% of the people surveyed said that CONFIDENCE was the main factor in how attractive a woman was. Yeah, that's what I thought too. But check this out . . .

In the SAME study, 67% of people said that good looks are what matter most. Again, I know what you're thinking. Those numbers don't really add up. But this is QVC people, not Harvard Medical School.

And also, it seems like people were allowed to pick different factors that contributed to their idea of what makes someone beautiful. So it sort of makes sense.

Anyway, here's how they ended up with the whole, '31-is-beautiful' thing: 47% of the people surveyed ALSO equated stylishness with beauty.

So according to the poll, the average 31-year-old still has youthful PHYSICAL beauty . . . they have more confidence than they did before . . . and they have a better sense of style than teenagers or people in their 20s.
