1. Wear Red

Men, like women, are more sexually turned on by wearing red. According to a study conducted by Dr. Andrew Elliot, simply wearing the color red or being bordered by a rosy hue makes a man more attractive and sexually desirable to women. The color red is associated with power, which lures women to men, although, they remain unaware of this arousing effect.

Ever wonder why Brad Pitt and George Clooney attract so many women? Their stubble exudes maturity and manliness, according to a study conducted at the University of South Wales. Men, ditch the razor, and let your beard grow just a bit, but steer clear of the Brad Pitt beard circa 2010.

3. Sit Up Straight

Being handsome has become easier than most men think. Physical appearance is not the only aspect of attraction: Personality and body language can influence how others see us, so it's important to maintain good posture, according to Dr. Jeremy Nicholson, Business Insider reported. Men, it’s time to take your mommy’s advice and sit up straight.

4. Smile Less

Although a smile could be warm and inviting, women tend to perceive men who smile as less dominant, according to the University of British Columbia. Men may have better chances of attracting that special lady if they swag or brood, which can help explain the enduring allure of bad boys. For those who do online dating, it’s time to update your profile picture. Just don’t look depressed.
