Garner was a guest on NBC's The Tonight Show, where she explained that getting into her dress was far less glamorous than one might think. "This was Versace, and they made it just for me. Do you know how they make it? See how I have a waist right there? I don't have one in real life anymore," she joked "What they do is they move your organs around. There are basically two men who come in with screwguns, and they screwed me into a metal corset—this isn't true, but it was a metal corset and it did take two Italian people. The next thing you know, my ribs were compressed."
"Like Spanx?" Fallon asked.
"No, dude! It's not like that. It's so intense!" the Miracales From Heaven actress, 43, told him. "It's very intense. It's not like Scarlet O'Hara. There's metal inside and these people just kind of move your ribs and they move your liver out of the side and they pop you in. To keep you in place, you step into a bodysuit first, which is like the bottom of a leotard, but it's a thong."
