Oops my torso..

I have seen this once too many times and couldn't help thinking why do they do that? What eh hold on...Why do the pretty and not so pretty women keep tugging that short top every now and making unsuccessful attempts to cover that skin that is visible. The poor little top stretched beyond its limits coz of that incessant tugging keeps going up ever so often. Are they conscious that they are being watched?
What was the purpose of that top which was a tad short in the first place, that women wear? Why did they buy it in the first place to cover up or to flash that skin or probably it shrunk after the first wash.
Or did the trial room not have a mirror at the store they picked it up from?
So which of the above is it :-)Anyone care to explain :-):-)

If the intent of picking it up was to bare some skin which I think is the best answer then why do they keep pulling it down when they have managed to get that much needed attention?
