Heidi Klum's crimson mini dress is the ultimate party dress

Heidi Klum continues to dominate the Cannes Film Festival this week, proving that one eye-catching look isn't enough. Klum, who had already made a grand entrance, stepped out again, but to support a cause close to her heart: the Soul of Brazil and Foundation for Brazil, a charity dedicated to connecting leaders and organizations working to support disaster-stricken Brazil Provide support to citizens affected by sexual flooding. She just accidentally stole the spotlight in the process (an occupational hazard of the world's supermodels).

At the organization's event hosted by superstar Alessandra Ambrosio at La Petite Maison restaurant, Klum wore a low-cut red mini dress with strategically placed rosettes. She teased the look with a boomerang on Instagram, capturing the style in motion and leaving fans breathless — and the photos from the charity event were equally stunning.

Fashion choices aside, Klum wouldn't be herself without her signature sex appeal. We all know she loves her signature blonde beach waves, and this time is no exception. Just last week, she showed off her blonde curls on the Cannes red carpet; she's channeling the same vibe in Instagram photos promoting her hit show Germany's Next Top Model .

The makeup, however, was a pure bombshell moment: think stunning black eyeliner, glittery lids, and red lipstick. Side note: flawless nude manicure and that giant diamond on your finger? Casually.

Last week, the America's Got Talent host wore a satin red ball gown with a sweetheart neckline by Saiid Koheisy to attend the opening night of the film festival and the premiere of the film "Second Act." Stunning appearance on the red carpet.

But if there's one thing I know about embellished supermodels, it's that they always look their best at an event, whether it's a big party or a casual moment. Because of the way Klum arrived at Cannes Airport yesterday? It makes me question the way I dress.

Honorable Mention: Her Chic Airport Outfit

After debuting in Cannes last week, Klum was spotted back in Nice wearing a chic black satin two-piece skirt suit, which she paired with a black leather jacket, clogs and oversized sunglasses. No matter how far she's just come—her look screams "I've arrived, and I look effortlessly chic while doing it."

So next time you're shuffling to the airport in yesterday's sweats, you might want to think again and ask yourself, "WWDH?" (What would Heidi do?) The answer might involve an outfit that makes you look like you're in the magazine character's clothing.
