Whether it's a smudge of lipstick or a bright dress, the colour red has long been associated with power and seduction.
But it's apparently not just a cliche - wearing red does actually make women feel sexier, according to a study.
One in four women surveyed said they chose a red outfit when they wanted to look seductive, making it the most popular colour for impressing a potential partner.
One in six said wearing black made them feel sexiest - and the same proportion chose pink. The survey of 2,000 Britons found women felt the most confident wearing black - perhaps explaining its popularity in the workplace. Men also favoured black when they wanted to feel at their best, with one in three choosing the colour.
Yellow was the most unpopular colour for both genders - with one in three respondents claiming they would never wear it.
