Man, when will the creators, producers, directors, etc.....
Send in a woman without having her show cleavage?
Doesn't matter who she is - if she's a main character, you have to have her wearing something to show off her form, or her 'forms.'
The woman, whoever she is, is accomplished, assertive, skilled, intelligent, but what do WE want to see? YEAH! You know it... cleavage. Her dress has to hug her body. She's wearing heels. Doesn't matter if she's the head of a law firm, doctor, whatever! And if she's really really going to try to vary 'the look,' put a little jacket on her and let it fall open enough to show that she's got something like a camisole on under that!
