If you a person is groomed as per conservative values for him or her wearing mini skirt and tank tops woudl like blamshepy, however a liberals would not feel it is scarliegious to wear skimpy or short clothes, they would go about with what they like to wear whether apporpirate to the ocassion or not, for they are concerned about how they look and not what others feel about them.
I believe society consists of both liberals and otherwise and we need to respect everybody's sensibilites and sort of follow a middle path.
The person wearing should take due care as well as the society should give the freedom of choice to all without making any issue out of it.
