These are some of the weirdest things that clothes can apparently do. All the observations were found online. 
According to a 2012 study in the US, if you are wearing the white coat of a doctor, your ability to pay attention increases sharply. If you wear a white coat that you believe belongs to a doctor, your ability to pay attention increases sharply. But the wearer has to know the history of the coat. The same study said that if the coat was thought to belong to a painter, the same spike in attention was not witnessed.

The rest claim to be general truths. 

♦ A man in a bespoke suit apparently inspires more trust. So much for class.

♦ Women are said to wear jeans twice more often when upset rather than in times of happiness. 

♦ Superman T-shirts allegedly make their wearers feel stronger.

♦ A woman is said to be more likely to get the job is she is drssed in a masculine way.

♦ Some wearing red is approached faster than someone wearing blue. Really???!!!! 

♦ The last and the best: Women do not fare well solving algebra problems when they are in swimsuits. But what happens to the men?
