Kimora Lee will be walking in today’s Red Dress Collection fashion show

Kimora Lee will be walking in today’s Red Dress Collection fashion show at 7pm, including Heidi Klum, Kim Kardashian, Raven-Symoné, Jewel, Kristin Chenoweth, Elisabeth Hasselbeck, Felicity Huffman…and, Dynasty legend Joan Collins too.

Maybe that’s why Kimora looks like she’s been losing a lot of weight.

The list of designers that have created dresses for the show is similarly stellar, featuring Donna Karan, Oscar de la Renta, Michael Kors, Zac Posen, John Galliano, Monique Lhuillier, Badgley Mischka, Marchesa, Tracy Reese, Rebecca Taylor and more.

The outfits the celebs will be wearing will be auctioned off at the Clothes Off Our Back website, with proceeds benefiting the Foundation for the National Institutes of Health, earmarked for research and awareness on heart health for women.
