When Stana Katic stepped out for a PaleyFest event in late September, the Castle actress debuted a shockingly sassy new ‘do. Now, to go along with her dramatic hair transformation, the 35-year-old star is getting playful with her clothes!

On Tuesday, October 8, Stana walked the red carpet at the premiere of CBCG: The Movie in NYC. Typically one to gravitate toward clean and classic styles, Stana stepped outside her comfort zone in a belly-baring number designed by Donna Karan.

Stana flaunted her abs in the bustier-and-skirt ensemble, which she paired with sophisticated stiletto heels. While the outfit itself was unexpected enough, the actress took it one step further with a retro, slicked-back bob.

Back in April, Teen Wolf star Holland Roden wore a similar version of the Donna Karan dress when she served as red carpet host for the 2013 MTV Movie Awards.

The 27-year-old actress kept her look sleek and chic, donning Art Deco-inspired jewels and Ruthie Davis two-tone heels. Though Holland’s fiery locks are often the centerpiece of her look, the simple parted style didn’t compete with her outfit.

Who do you think rocked the Donna Karan number best?
