After losing 75 pounds, Kirstie fulfills her promise and proves she is bikini ready! "You look beautiful," Oprah says.

The prospect of wearing a bikini in front of millions motivated Kirstie to work out even harder with her trainers, she says. When the time came to go on stage, Kirstie says she wasn't worried about her body—just her pantyhose!

Kirstie says she searched far and wide for a pair of pantyhose to wear under her bikini. She finally found a pair without a center seam but didn't realize they were "low rise." Backstage before the show, she says she was worried that her hose would slide down. Thankfully, there are no wardrobe malfunctions to report!
