Lily Collins drew public attention at New York Fashion Week after arriving at the Calvin Klein show in a sequined, feathered two-piece that left her midriff exposed, prompting social-media users to express concern about her slim waistline.

Photos and video of the 36-year-old actress, known for the Netflix series Emily in Paris, circulated online and generated comments from fans who urged her to "eat something" and questioned whether she had always been so thin. One user wrote, "Please Lily, I mean this sincerely, get help," while others posted, "Was she always this thin?" and "Wow! Too skinny!" Critics also commented on her outfit, which included strappy metallic heels and a dainty handbag.

Collins has been public about prior struggles with disordered eating. In her 2017 memoir, Unfiltered: No Shame, No Regrets, Just Me, she described suffering from eating disorders as a teenager and detailed physical effects including brittle hair and nails and an interrupted menstrual cycle. Excerpts from the book also recount her fear that the disorder had harmed her fertility. Collins has discussed the origins of those struggles in the context of family events and personal pressures.

The actress has previously taken on roles that required significant weight changes. In 2017 she spoke about preparing to play an anorexic patient in the film To the Bone, saying she lost more than 20 pounds for the role while working with a nutritionist to do so safely. She has said the experience required emotional work and supervision to address the role responsibly.

Representatives for Collins did not immediately respond to requests for comment on the NYFW appearance. Public reaction on social platforms was varied, with some fans offering support and others expressing alarm.

New York Fashion Week often draws heightened scrutiny of celebrities’ appearances, with outfits that emphasize particular silhouettes frequently prompting discussion across social media. Collins’s case drew attention in part because of her prior public statements about eating disorders and body image, which many readers referenced in the wake of the event.

Collins continues to work in film and television while engaging publicly on topics of mental health and personal recovery. Her past accounts, including the memoir and interviews about To the Bone, remain the principal sources documenting her history with disordered eating and the professional steps she said she took when weight changes were required for a role.
