Apropos of Valentine’s Day, new research takes an interesting look at how clothes can determine femininity. But the study goes a little deeper – literally – to look at how different types of underwear, rather than outerwear, affect a woman’s feeling of femininity. Though underwear is often hidden under clothing, the authors say that for the woman wearing them, the garments can play a key role in her sense of sexuality. So men, before you make your annual Victoria’s Secret run, take into account the results of the study. Buying the slinky, red thong just because the Victoria’s Secret mannequin is wearing it may have the unintended effect of deteriorating, rather than inspiring, a feeling of sexiness in a woman.
