Barbie is making her Kentucky Derby debut in style.

Churchill Downs says it's teaming with toy maker Mattel to create the Kentucky Derby Barbie doll.

Churchill said Thursday the doll will wear a floral sun dress, faux pearl necklace and spring sandals, topped with an oversized white hat.

Churchill and Mattel will give Barbie collectors a chance to own their own life-sized Kentucky Derby Barbie replica hat.

Milliner Christine A. Moore will create up to 135 replica hats to commemorate the 135th Derby and the Derby Barbie.

The first hat will be auctioned off through the Clothes Off Our Back Foundation. The rest will be available on the Derby's web-base store.

The Derby is set for May 2 at the famed Louisville track.
