From Ralph Lauren to lululemon, there were big-name designers showcasing their chops at the Opening Ceremony for the 2024 Paris Olympics on Friday.

Yet it wasn't simply a case of those superstars leading the way in France, as so many nations brought unique looks to a city widely deemed the fashion capital of the world.

Yes, the United States and Canada rocked couture on Friday, but nations like Mongolia, Nigeria, and Czechia were among those to impress with their unique style.

Let's take a peek at some of the eye-catching looks from Paris.

Ralph Lauren had some ideas to make the American team look pop in Paris (For a closer look, see some of the unveiled details from back in June).

Here are Lynn Williams, Lindsey Horan, and the USWNT showcasing the legendary designer's fit:

And, of course, Noah Lyles put his own spin on the look.

The medal hopeful painted his goals into existence with the letters I-C-O-N on his fingernails and a necklace adorned with the Olympic rings.

Canada's outfits were designed by lululemon and built to adapt to the weather. The outerwear can be adapted from a bomber-style jacket into a poncho, or can be worn strapped around the front of the body.
