From Size 14 to Size 4, Kirstie Alley Debuts at New York Fashion Week Catwalk (PHOTOS)

With a slimmed-down figure Kirstie Alley made her runway debut at the Zang Toi Spring/Summer 2012 show during the 2011 New York Fashion Week.

She hit the catwalk during Zang Toi's fashion show in an elegant black top and leggings and closed the collection in a jewel-bedazzled royal blue coat, cinched at the waist, Los Angeles Times reported.

Celebrating her recent weight loss Kirstie Alley said her dramatic weight loss followed a long battle with the problem.

I've lost 100 pounds! a svelte 60-year-old Kirstie Alley told Entertainment Tonight on Tuesday.

I feel like I'm back in my element. I honestly didn't even realize what I looked like, she said.

Kirstie Alley said she was now a size 4, down from a size 14 during her time on Dancing with the Stars.

I bought these dresses from size 14 to 4, she told ET. [They were] all the same dress, and I said, 'You know what I really want? I really wanna be in this dress in a 4!'

The public has seen her rollercoaster weight loss and gain, but the most notable was during her 2011 participation on Dancing with the Stars, where the dress she wore in her debut had to be taken in 38 inches by the time the finale came.
