Jane Fonda, 85, looks glam in a structured jacquard gown at the Vienna Opera’s annual ball

Jane Fonda put on a glamorous display when she attended the Vienna State Opera’s annual ball in Vienna, Austria, on Thursday.

The legendary actress, 85, looked elegant in a structured jacquard dress that cinched at the waist before falling to the ankle.

She teamed the stunning ivory number with a pair of metallic stilettos and carried a black velvet coat over her arm.

Jane accessorized with a pair of dazzling hoop earrings and carried a cream clutch.

Her shiny gray hair was perfectly coiffed and she finished off her sophisticated look with a hint of shimmering eyeshadow.

The actress sat in the audience where she took some photos with her phone and greeted fans.

Jane is a big part of why working out and being fit became such a big part of pop culture and in a recent interview she detailed her reasons for working out.

The movie star launched the Jane Fonda workout in 1979 and now, 44 years later, the Grace and Frankie star is still touting the benefits of working up a sweat.

“You have to be able to, you know, make love,” she said at the opening of H&M’s Move Studio in Brooklyn on Wednesday. ‘I do not remember much [about that]but I remember that you need flexibility!

Still doing her iconic workout to this day, Fonda was named the face of H&M’s Move campaign last year and four decades after she made leotards popular among suburban women, she still extols the virtues of get up and move.

“You have to stay strong,” he said. ‘I have a grandson who is three years old and I can still pick him up.

‘I mean, I have to bend my knees and, you know, it takes a long time to get it up there, but I can still get it up. You want to be able to carry your own bags.

But the Barbarella star wasn’t always a fitness fanatic. In fact, she didn’t start exercising until she was in her 30s.

“I didn’t know it was important to do it until I was 30,” the 80-year-old actress told Brady. “I had a ‘constant period’ all through school so I couldn’t do gymnastics, anything to get out of gymnastics.”

‘It wasn’t until my late 30s [or] In the early 40’s I started to get really active and life before I was active wasn’t as good as when I started moving.’

And being flexible isn’t the only reason Fonda fell in love with fitness. She also found that it helped her mood.

“I come from a long line of really depressed people, and the best way to combat depression is to keep moving,” she said.

The 9 to 5 star announced in December that the non-Hodgkin lymphoma he was diagnosed with in September was in remission.

“I won,” he commented.

And in light of age and health, the On Golden Pond star now looks healthy, not skinny.

‘Wanting to be skinny as a bone is not good. It’s not good for your health, and it’s not good for your mind to be so private,” she said.
