stripping compulsory in bollywood?

Hema Malini in an interview said that heriones these days have to show of their body if they want to get anywhere in bollywood
they have to wear small clothes and all that...
after all...look at esha deol...
only after she kinda stripped in dhoom she's been getting all these offers...so is rimii sen after dhoom...udita goswami, neha and all those others...

is bollywood getting cheap in that way...cant a heroine wear full clothes and still do well....and what with all the sex and kisses in the movies..

what do think...are short clothes becoming more necessary for heroines to survive in bollywood
