Women dress like whores when they ovulate, but only if they're single. High sociosexuality (being a whore) predicted dressing like a whore.

Evidence that men correctly interpret whorish clothing as a visual cue for female sexual availability and infidelity (re. latter: see e.g. this paper).

"women closest to ovulation in their high-fertility session who were not in committed relationships revealed a markedly greater amount of skin on the illustration during high fertility than during low fertility"

"Revealing clothing was preferred at high fertility by single women rather than by partnered women, suggesting that shifts in choice of clothing may reflect shifts in social motivations that are more relevant to single than to partnered women."
