Women are more attracted to men who surround themselves with other attractive women, a study found.
Their presence gives men a 'halo effect' which confirms he is suitably dating material, and they need look no further.
The effect – known as 'mate choice copying' in the animal kingdom – is so strong that in America so-called 'wing women' can be hired to enhance a man's appeal in bars and at clubs.
The study, led by psychologist Dr Sarah Hill of Texas Christian University, Fort Worth, found: 'Women find men more desirable when they appear to be desired by other women.
'Women use the presence of a man's mate as a cue to his own quality.
'Females observe a romantic or sexual interaction between a male and another female and preferentially choose that male as a mate.'
'Women perceive men with attractive romantic partners to be more desirable than when depicted alone because women infer such men possess unobservable qualities that women desire in their mates.
'This result suggests that human female mate choice copying might emerge from a process wherein women use the interest of another woman as evidence that a man possesses unobservable qualities that make him a desirable partner.'
