On Wednesday, the Sports Illustrated cover girl attended the 2013 Style Awards in New York City. The award show is the first event of New York's Fashion Week -- and all of the attendees brought their fashion A-game!
The 21-year-old bombshell was presented with the coveted Model of the Year award by supermodel Christie Brinkley. The dynamic duo posed for photos together on the red carpet and each looked absolutely gorgeous at the fashion event.
Kate wore a plunging Altuzarra black dress for show and the sheer slit kept her ensemble both sophisticated yet sexy. Upton finished her look with Jimmy Choo pointed pumps and wore her hair in voluminous curls.
But Christie didn't let her younger protege outshine her -- Brinkley looked absolutely stunning in a curve-hugging grey lace gown and styled her golden tresses in curls. Can you believe Christie is 59-years-old? Sign us up for whatever she's doing!
The blonde beauties weren't the only stars at the event. Nicole Richie showed some skin in a studded pant-top combo, Adrienne Bailon worked her inner Jessica Rabbit in a sexy red dress and newly pregnant Rachel Zoe played it safe in a beaded black strapless gown.
Zoe was honored with Stylist of the Year.
