She wore an itsy bitsy, teeny weenie, neon green bikini.

Barbara Corcoran, 76, flaunted her stunningly toned figure in a swimsuit as she shared a funny Instagram post Monday.

The “Shark Tank” star shared side-by-side photos of herself in extremely different weather situations just one day apart. In the first photo, she waved on the beach in an eye-catching two-piece, and in the second photo, she was bundled up in a long tan coat, jeans and a scarf.

She captioned the first photo “August 31” and wrote “September 1” on the second.

“This is what being a New Yorker feels like!” she posted. “My heart says summer but my calendar says Fall…”

Corcoran’s humorous take on the changing seasons earned a laugh from “Real Housewives of New York City” alum Kelly Bensimon, who commented, “yes! That’s exactly what it’s like” alongside several laughing emojis.

But several fans focused more on the businesswoman’s glamorous appearance, including one netizen who wrote, “You look fantastic.”

“Omg she’s sexier than sexy,” another Instagram user commented. “Whatever Barb is doing she’s perfect.”

Corcoran did reveal exactly what she’s doing to maintain her looks back in July, and it isn’t cheap.

The real estate investor shared the expensive list of procedures she’s had performed to combat aging. She admitted that she’s had three face lifts, a brow and eye lift, neck lift and gets filler four times a year, among other services.

In May 2024, Corcoran told Page Six that she’s considered getting other body enhancements, including a fourth face lift for her 85th birthday and anything else she “can sign up for.”

“I’m thinking of enhancing my figure,” she said at the time. “I would like to have a bigger chest, bigger hips, bigger butt.”

However, she acknowledged that she’s not sure she could “withstand” multiple surgeries.
