It was a case of "free the nipple" for supermodel Gigi Hadid, who has turned heads in Paris without a bra.

Wearing a high-neck sheer lace top under a long winter coat, Hadid, 23, made quite an impression on the catwalk for French luxury brand, Lanvin.

The New York-based model — who recently split from former One Direction singer Zayn Malik — sported a vanilla-colored outfit complete with power shoulders and buckles from the brand’s fall/winter 2019 collection at The Musée Cluny.

Not one to shy away from showing some skin, Hadid flashed her nipples under a see-through lace top during the runway presentation.

The show marked the first collection by Lanvin’s new creative director, Bruno Sialelli, with sheer lace, neutral tones and dark-lensed statement sunnies also trending.

Hadid recently opened up to Elle about her relationship with her younger sister, Bella Hadid.

“Bella and I have very different styles,” Hadid told the magazine.

“A job that wants Bella is not a job that I’m the right look for, so I never took that personally.

“In a lot of ways, she inspires me. We learn from each other.

“I feel very lucky to be able to have a piece of home in my work environment.

“We are each other’s biggest fans. It has been a huge joy of my life to watch my little sister flourish, and to help when I can!”

Casting Hadid and rising star Kaia Gerber, 17, for the runway was sure to add a fresher look to the 130-year-old brand, for which Sialelli, 31, is the fourth designer in as many years.

“We know Lanvin is an eveningwear house where you find beautiful flou and colors,” Sialelli said pre-show, according to Women’s Wear Daily.

“But Jeanne (Lanvin) was also one of the first to do a wide proposition of women’s wear, menswear, and sportswear, curtains, and furniture.”

The new season collection had — at times — an androgynous style, which Sialelli said was representative of the changing face of retail.

“This is how we shop today; women go to the men’s department to get a shirt, men go to women’s for a beautiful pink sweater,” Sialelli told WWD.

“I buy Celine jumpers. They don’t want to hear it’s men’s or women’s.

“They don’t really care. It’s not about gender fluidity, it’s just a fact. It’s how people are shopping now.”
