Its the ambience and environment. All of us are actors in our way, that doesnt mean we wear undies and goto a marriage or public meeting just because I wore at beach party with my friends who already saw me nude. The same friends of mine would redicule me.
Its not about Shriya (big fan of her shapes), but going to casual or in party wear to a public gathering is being out of sync. Especially the mumbaites (Suniel shetty in a southern awards function came with rags and unbuttoned fly, people were like where did this monkey (we are of same race) come from).
