Certain style trends only work for some fashion mavens, but for everyone else, these four items are must-have pieces. These basics are effective at making you look attractive and the evidence to this is actually backed by science.

FOR THE LADIES

1. High Heels

Did you know that the high heels were first designed by a man for men? Back in the 10th century, the footwear was essential to horseback-riding as it kept a man's legs and feet clasped in the stirrups, according to Slate. Overtime, sexy high heels, which are also called stilettos, have become a woman's shoe obsession that has helped heighten attractiveness, according to a study done in 2014.

2. Red Lipstick

Psychology has linked the color red to positive energy, strength and motivation and when it comes to beauty, red lipstick is the color that draws more attention from the opposite sex, based on a University of Manchester study, as reported by HNGN.

3. Little Black Dress (LBD)

Every woman needs a little black dress, which is said to be a favorite go-to piece for first dates or job interviews, according to a survey conducted by Buy T-shirts Online. Respondents said that they believe an LBD exudes confidence, capability and trustworthiness.

FOR MEN

4. Men's White Shirt

Men in plain white shirts appear to look cleaner, well-toned and dapper to the ladies, so says a study done by researchers at Nottingham Trent University. White shirts apparently create an illusion that gives men broader shoulders and a slim waist; they accentuate features of masculinity, according to Telegraph.
