Her other roles include the films Entourage (2015), We Are Your Friends (2015), I Feel Pretty (2018) and Welcome Home (2018), as well as the miniseries The Spoils Before Dying (2015) and the anthology series Easy (2016).

She has since walked on the Paris Fashion Week runway for Miu Miu and Milan Fashion Week for Bottega Veneta, Dolce & Gabbana, and Versace.
Ratajkowski appeared in a Buick Super Bowl commercial during Super Bowl 50 (2016), and has become the spokesperson for brands such as DKNY, The Frye Company, Kerastase, Paco Rabanne, and DL1961. She is an advocate for women's health issues as a spokesperson for Planned Parenthood. As a self-identified feminist, Ratajkowski has received both support and criticism for her views on sexual expression.
