Selma Blair electrifies NYFW in purple leather dress at Christian Siriano runway show

She's normally seen casually attired while playing with her toddler son.

But all eyes were on Selma Blair at Mercedes-Benz Fashion Week on Saturday where she electrified the Christian Siriano runway show in purple leather.

The glammed up 41-year-old displayed her tiny waist in the sleeveless wrap dress, which she paired with snakeskin T-strap heels.

The Grammy-nominated star rocked a smoky eye, nude lip, and put her blonde locks into a sleek updo.

While backstage, Selma met up with the man of the hour, best known for winning Project Runway's fourth season.

Some of the newly engaged 27-year-old's famous clients include Sarah Jessica Parker, Lady Gaga, Rihanna, Victoria Beckham, and Taylor Swift.

'What a gorgeous show and so good to see old friends. @csiriano you killed it,' the Cruel Intentions actress later tweeted to her 48,000 followers.

Blair - born Selma Beitner - is quite the fashionista having fronted campaigns for Chanel, Miu Miu, and GAP.

Not seen Saturday was her two-year-old son Arthur Saint Bleick.

However, Selma might be able to exact a rare kind of revenge on her bitter former co-star Charlie Sheen.

Two and a Half Men's series creator Chuck Lorre was not opposed to the idea of Blair playing Charlie Harper (Sheen)'s long-lost daughter.

'I guess she’s available, huh? She’s a good actor,' the seven-time Emmy nominee told Screen Crush at a TCA press tour in July.
