"I have not a stitch of makeup on," Ross told ET. "I don't work out in makeup, although I do wear a red lip, because I feel like if you're going to look in the mirror, you want to see a little pop!"
The Emmy nominee has come a long way from insecurities that used to plague her. She admitted to ET that she once struggled with body image issues.
"I have had an internal struggle as a young girl of not feeling comfortable in my skin, and I just happen to be one of those people who has fought hard to love who I am," Ross said. "My size fluctuates between a large 4 and a 10."
Ross put Turner through the wringer at the Tracy Anderson Method Studio in Studio City, California, which is sure to pay off on the Emmy red carpet. Ross admitted that she became emotional while trying on her dress, as this marks her first nomination.
"I am 43 years old. I have not been engaged or gotten married. I haven't had a child and there's not a lot of things in our culture that allows single people to be celebrated," she explained. "It was this moment that was really beautiful."
And Ross is keeping her eyes peeled, for better or worse.
"Today, I was driving my car and there was this man walking without a shirt on, and I was like, 'Focus on the road, girl,'" she said. "And then I saw myself looking in the rearview mirror, trying to see his face. It was ridiculous. I was like, 'Oh God!'"
