The supermodel was breathtaking in a hot pink strapless, voluminous, tiered tulle gown for the amfAR Gala during the Cannes Film Festival. The dramatic gown featured a high-low hem with a long train, which she detached to reveal a mini version of the dress.
Jenner's dress is part of couture designer Giambattista Valli's limited-edition collection with H&M. The mini version, along with eight other looks, will be available to shop on H&M's website and in select stores on May 25 as a pre-drop, which quickly sold out! The full collection will launch on Nov. 7. The capsule will also include ready-to-wear, accessories and menswear.
Although Jenner's dress is priced at $399, it's a complete steal compared to Valli's haute couture pieces, which can cost up to six figures.
The 23-year-old KUWTK star was joined at the A-list soiree by momager Kris, who rocked a satin ivory pantsuit.
