According to Martiw Haselton, professor of psychology at UCLA and lead researcher, "near ovulation, women dress to impress."
The recent study denies the theory claiming the females of the human race are the only ones that show exact behavior during fertile periods as they do during menstruation.
Experts monitored 30 female students aged 18 to 37. Participants at the study were not revealed the real reason for which they are examined.
They were asked to give urine samples at the laboratory regularly, so that scientists knew the menstrual circle's day each woman was passing through.
Each female was photographed twice. One picture was taken during the most fertile period and the other one was taken during the least fertile period.
Scientists observed that at ovulation: "They tend to put on skirts instead of pants, show more skin and generally dress more fashionably. We did see a little bit more skin. It was my impression that women were just dressing a little bit more fashionably, but not sexier."
Moreover, people analyzing the photographs agreed with the US scientists.
42 men and women were required to pick from each pair of the two pictures, the one in which the person photographed looks better. Surprisingly, most of them preferred the photo taken during ovulation.
"The thing that is so remarkable about this effect is that it is so easily observed," said Martiw Haselton.
