Researchers at the University of California at Los Angeles have found that women subconsciously dress their best when they are the most fertile. According to a recent article in DailyMail.co.uk, "the discovery overturns the theory that women - unlike other female animals - always hide signs they may be ovulating."

Published in the journal Hormones and Behavior, the official Journal of the Society for Behavioral Neuroendocrinology, the study took thirty female university students, and photographed them before, during, and after ovulation. None were aware of the purpose of the study. Another group of both men and women were then asked to choose the photo in which each woman was trying to look their most attractive. 60% of the time, judges picked the image taken when the test subject was most fertile.
