The Journal of Experimental Psychology says that the colour, comfort, fit and style of our clothes can directly affect our confidence levels. More than 96 per cent of people report a change in their emotional state with a change in their style of dressing. 

For example, a group of doctors were handed a 'white lab coat' and asked to perform a series of tests. Another group of equally qualified doctors were asked to perform the same tasks without the 'white lab coat'. The group that wore the lab coat performed flawlessly, while the ones in casual clothes made more mistakes. This was repeated with several large groups of people, and each time, the result was the same! 

Simple clothing cues, such as a big smiley face on the t-shirt or sweatshirt, are proven to make one significantly happier and more relaxed. People who changed into workout clothes on waking up feel more ‘charge up’ to exercise.
