Jennifer Aniston knows how take the boring out of wearing black. The actress stunned last night in a Dolce & Gabbana black pant suit at the NYC premiere of Five — her producing/directing project alongside Demi Moore and Alicia Keys — and bared some serious cleavage with her black lace bra visible along the neckline of her tight vest! Jen's man Justin Theroux went along for support!

Justin escorted Jen to the premiere, but supported from the sidelines, skipping photo ops on the red carpet with his leading lady.

Also in attendance, actresses Patricia Clarkson and Jeanne Tripplehorn who star in the films directed and produced by Jen, Demi and Alicia!

Five is an anthology of five short films exploring the impact of breast cancer on people’s lives.

Demi made a quick change at the premiere arriving in her leather pants and changing into a black hip-hugging dress.

Swizz Beatz joined Alicia for her big moment.

The ladies covered the September issue of Glamour magazine and opened up on the project.

"We were intrigued by the challenge of creating short stories that would defy audiences’ expectation of the subject,” Jen recently told Glamour. “We wanted to balance the drama with humor and irreverence because that’s what’s helped our friends who’ve faced this get through their treatment.”
