García Swisher made her debut in the Nov. 3 episode of the ABC fantasy series and admitted that her costume came with a corset. "I had JUST had a baby so I was grateful for it!" the TV star told one of her Twitter followers.

Speaking to E! News last week, García Swisher said she was a bit nervous about wearing a bikini top and mermaid fins on camera. "Well, I just had a baby. I just took a deep breath and I said this is the little mermaid and she's a little voluptuous right now and I'm going to go with it."

"It was a dream," she added, "and of course I had [Ginnifer Goodwin] to hold my hand when I realized, 'Oh my god, I'm half-naked!'"
