Lili Reinhart wears a sleeveless blue sheer dress at Paris Fashion Week… after demanding that “average-sized arms” go “mainstream.”

Lili Reinhart dared to go sleeveless at Paris Fashion Week celebrations on Monday, just two weeks after calling for “average-sized arms” to become “mainstream.”

The 27-year-old Riverdale alum exited Hotel Costes looking beautiful in a baby blue eyelet ankle-length dress, brown pumps, and a red Lancel Paris 1876 handbag, selected by stylist Mimi Cuttrell.

Hairstylist Ericka Verrett styled Lili’s elegant updo, leaving a few tendrils to frame her face.

Makeup artist Francesca Angelina Brazzo brought out Reinhart’s large bluish-green eyes and natural brows and applied a rosy hue to her lips.

The Ohio-born blonde was flanked by a stocky bodyguard dressed in black and another man in a silver silk blouse.

Represent! Lili Reinhart dared to go sleeveless at Paris Fashion Week celebrations on Monday, just two weeks after calling for “average-sized arms” to become “mainstream.”

“I wish there were more average-sized arms in mainstream media for women,” says Lili – who has 32.1 million social media followers – tweeted on September 14th.

“My body dysmorphia is going crazy because I feel like my arms should be half the size they are now?” We’ve glamorized those skinny arms that most of us can only achieve by literally being an adolescent. “

Reinhart continuation: “I really wonder how anyone survives or gets through this life without suffering from severe BD.” Maybe it’s a cruelly amplified version combined with my OCD, but damn.

“The amount of time I’ve wasted thinking about my arms over the last few months is insane. I wanted to spread my own thoughts to let other women know they’re not alone.”

The Look Both Ways producer and star, who also suffers from depression and panic attacks, considers her Instagram account a “safe space for body positivity and mental health awareness/acceptance.”

Lili later helped unveil Lancel’s SS/24 presentation themed “Saint-Tropez Futurama” as part of her official duties as the luxury leather goods brand’s global brand ambassador since April 6.

Reinhart proudly posed at the fashion event alongside Emily in Paris, actor Kevin Dias and German photographer Ellen von Unwerth.

Missing from the home-schooled Zoomer’s side on Monday was her boyfriend – La Brea actor Jack Martin – whom she had been dating since April.

On September 24, Lili posted a TikTok in which the 25-year-old Georgetown University graduate quietly explains how soccer works so she can offer tips on how to stop mansplaining by pretending you can’t hear what she’s saying say.

“Jack wants everyone to know this was a joke and he wasn’t mansplaining in real life,” Reinhart captioned her clip.
