Tatiana Maslany Wows In Sexy Cutout Dress At Canadian Screen Awards

Damn, girl!

On Sunday, March 1, Tatiana Maslany attended the 2015 Canadian Screen Awards wearing a dress that we won't forget anytime soon.

The "Orphan Black" star looked stunning in a sexy navy Greta Constantine frock that featured an asymetrical cutout overlay, a sweetheart neckline and a satin pencil skirt that hit just below the knee.

The 29-year-old Regina, Sask.-native completed her head-turning outfit with ruby red lips, sleek wavy locks with a dramatic side-part and strappy sandals that gave the ensemble some edge.

Not only did she win on the red carpet, but she took home the big award of the night. The brunette beauty won the Best Actress award (her second time winning in the category) for playing an astounding seven characters on "Orphan Black," which also picked up the Best Dramatic Series award.

Other celebs on hand that night included recent Oscar winner Julianne Moore, who looked gorgeous in a sleek black suit; "Rookie Blue" star Missy Peregrym and actress Sarah Gadon.

She's stunning:
