Marisa MillerA new survey reveals that a woman's attractiveness peaks at age 31.

The shopping channel QVC polled over 2,000 men and woman on, among other perceptions, the optimal age for feminine beauty. In addition to arriving at 31 being the age when women look their best, the survey also found that 70 percent of respondents cited confidence as a key factor in making a woman attractive; 67 percent mentioned physical beauty; and 47 percent pointed to personal style.

Since two-thirds of the women QVC surveyed agreed with the statement, "with age comes beauty," it's possible their answers to the optimal age question inflated the score in a direction most guys wouldn't agree with.

Then again, here is picture of 31-year old model Marisa Miller, who is looking better than ever -- and will put just about any 20-something to shame.
