Blame it on their envious bodies, miles-long legs, perfect curves, gorgeous faces, and the uncanny ability to pull off everything from the most couture gowns to the most avant-garde creations on the runway with absolute ease, but there seems to be an unspoken understanding that today’s supermodels should look nothing less than amazing every moment they step out of the house and onto the red carpet. It’s not fair, of course, but that’s the reality of our celebrity-obsessed culture. And 99 percent of the time, these models more than deliver on the fashion front, whether it’s Kate Upton wearing a gorgeous embellished mini dress or Cara Delevingne stunning in a black lace dress.

That's probably why it's so shocking when these ladies make a major fashion misstep, especially on a big stage like the annual Met Gala or the Cannes Film Festival. Sadly, beloved supermodel (and possible Harvard student) Karlie Kloss — who typically wows everyone in her slinky LBDs, classy ensembles, and dramatic ball gowns — did just this on Wednesday at the opening ceremony of the French film fest, walking the red carpet in a lacy, black and maroon Valentino gown that just didn’t live up to our impossibly high style standards.

With its super-sheer paneling, caftan-like fit, and drab coloring, the straight-from-the-runway gown did nothing to suit Kloss’s beautiful features or highlight her stunning figure. And considering that she was walking the Grace of Monaco red carpet alongside on-point stars like Zoe Saldana, Nicole Kidman, Blake Lively, and even Kendall Jenner, her Pirates of the Caribbean costume only seems that much worse.

Unfortunately, the gown didn’t look much better from the back. Though the open back did show off plenty of gorgeous skin, it also highlighted the baggy fit and her uninspiring flat sandals. (And 6’ 1” or not, no lady should wear flats to an event as high-fashion as Cannes.) Had the lace overlay simply been a dramatic cape in addition to a beautifully embellished jade green mini dress — or even a curve-hugging overlay instead — things may have started looking up for this Valentino number.

But at least her casually undone updo and those dazzling Chopard earrings somewhat saved it, right?
