The psychology of personal style

I read an article in the weekend paper on the psychology of fashion and how the way that we dress affects how we feel - something that isn't really that new to us, but it's important to realise that this does actually affect your personality.   Dr Karen Pine is a world leading fashion psychologist and her research is interesting.  There is a motivation behind what we wear and why.  It's all about projecting an image, be at work or play.   One of her findings on blue jeans was that for most woman these are known as their 'sad pants', that jeans get worn when woman are unhappy.  Apparently there is a correlation between depression and wearing jeans.

This topic does lead me to a question; why do people (particularly females) copy the style of another and wear this ensemble in front of the person they are copying??  (my pet peeve!!!)
