NEW YORK, Feb. 20 (UPI) -- Christie Brinkley showed off her toned body and flashed her bra in an orange dress she wore to Barbie's celebration of the 50th Anniversary of the Sports Illustrated Swimsuit issue on Monday.
The former supermodel, who turned 60 in early February, looked like a Barbie herself as she strutted and posed for photos at the event's pink carpet.
Brinkley complemented her form fitting dress with a black long-sleeve sweater, a black bra that peeked from her dress and orange and black heels.
After having her stunning look covered by several media outlets, the model turned actress shared a photo on Instagram explaining that she guessed Monday had been a "a good dress day."
While speaking to E! News about how she stays so fit at her age, Brinkley said she owed it all to the gym.
"I really do use it," she said. "It keeps me limber and able to get out there and do what I want to do, and be active."
