Researchers at Nottingham Trent University found that when men wore white t-shirts with a large black letter "T" printed on the front, women found them 12% more attractive.

 

The scientists suggested that the shirt creates an illusion that broadens the shoulders and slims the waist, producing a more V-shaped body that women found sexy.

 

In contrast, men wearing a top with an inverted "T" -- with the bar running around their waist -- were deemed up to 12% less attractive.

 

 

Forget everything you know about a husky voice being considered sexy -- women should use a higher-pitched voice when speaking to a man they're interested in.

 

Researchers at University College London found that men were more attracted to women with high-pitched voices because it conveys a smaller body type.

 

 

Women find less-stressed men substantially more attractive than their more-stressed out rivals, a study published in Proceedings of the Royal Society B journal found.

 

The researchers concluded that men with low stress levels are considered more attractive because handling a stressful situation suggests having a "strong" genetic makeup that can be passed on to children.

 

 

A study from last year revealed that roller coaster riders found their non-romantic co-riders more attractive after a whip around the track, according to The Daily Mail.

 

There was no difference for couples who were already romantically linked, so this trick only works with potential partners.

 

More than 1,000 people participated in the study, which first appeared in the Archives of Sexual Behavior.
