some girls wear all kinds of dress just for the fun of it..
some don't care at all...
some simple wear jeans and shirt in the office because of the weather... take our showroom for instance, i am trying to wear a respectable clothes slacks and 3/4 sleeves but the heat really is too much because every now and then the door in the showroom is open :(
some wear to impress...
some they want to be comfortable...
some wear sexy dress because they feel sexy and wants to flaunt it...

but if you want others to respect you then you have to wear proper clothes/dress not according to your moods but according to the dress code of the company...
but WTH.... its summer..its hot... what to do yane ;)
