Balmain's Oliver Rousteing kicked off Monday, May 7 (otherwise known as Met Gala Monday [1]) with a very important announcement: all the looks he created for the 2018 ball [2] will be auctioned off for charity as part of a partnership with (RED) to fight against AIDS. Olivier is dressing Jennifer Lopez [3], Alex Rodriguez, Trevor Noah, Juliette Binoche, Natalia Vodianova, Natasha Poly, and Julia Stegner, and their sure-to-be sexy outfits start at a $5K bidding price online [4].

100 percent of proceeds will go to the Global Fund, which aims to prevent the transmission of HIV during birth. Olivier talks about the collaboration in a video that you can check out below — and watch this space for the ensembles on the red carpet, all of which the designer confirms will be heavily influenced [5] by the "Heavenly Bodies: Fashion and the Catholic Imagination" theme.

"I'm inspired by religion. More than that, I'm inspired by love . . . I told my team, 'I know that these [looks] won't be ours at the end. But they're going to auction for (RED).' I wanted to make the most memorable clothes not just by their craftsmanship, embroidery, or cut, but because all of that would go toward helping kids survive. That was the point: to make the most spectacular creations to get the most money to save the most lives," Olivier told Refinery29.
