But that is what more than 20 years does.
And many fans quickly pushed back against the idea that Fonda should somehow be expected to resemble the woman who starred in Single White Female more than three decades ago.
Instead, a wave of comments celebrated what they saw as natural aging.
“And she look FANTASTIC!!!” one admirer wrote, praising Fonda for appearing without the polished styling typically associated with Hollywood.
The commenter went on to applaud her for appearing natural and hoped she would not be criticized simply because she no longer looked like a carefully managed celebrity image.
Others initially struggled to believe the photographs were really her.
“I don’t believe that’s her!!!” one person wrote.
“That can’t be her?” another asked.
Others thought she looked happy and healthy.
“She looks like she got her health back. She looks great,” one person commented.
Another simply wrote, “She actually looks wonderful still.”
