The TV regular recently took part in a The Hollywood Reporter panel chat with fellow funny girls Amy Schumer and Lena Dunham when she was asked to recount the worst thing she had done at an audition.
Ross said, "I tested once for a network show to play a lawyer, a Harvard-educated motherf**kin' lawyer, OK? I wore a skirt suit and heels. Seemed appropriate.
"Then there were many discussions about my hair. They'd printed up all these pictures of me from 15 f**kin' years ago and had me in and out of the bathroom trying on clothes. They finally pick a skirt - the shortest I brought. Then got a T-shirt from one of the people in the office. The woman says, 'Hmmm, your boobs'. I was like, 'I didn't bring a bra for this T-shirt'.
"She screams down the hall, 'Who wears a 34B?' I put on someone else's bra, a size too small, and somehow auditioned. I remember wondering, 'What did I just allow myself to do?'
"The other actress (who auditioned) was dressed like she was going to a club and got the role. It was one of those moments where you're so confused and humiliated. But that's part of the biz."
