Jennifer Aniston leaves little to the imagination as she reveals black bra under tight white vest

It has long been her favourite shade, and in the last few days  hasn't strayed far away from wearing black.
But today the actress stepped out in a different monochrome hue, slipping into her other preferred staple  - a white vest.
But the 42-year-old Friends star clearly couldn't part with some kind of dark accoutrement, wearing a black bra underneath.

The undergarment peeked through Jen's singlet, which she paired with some faded blue jeans belted at the waist with a brown leather belt, and a grey sweater wrapped around her waist.
The Friends star went make-up free for the outing and carried her favourite leather Chloe bag and a Smart Water, for which she is the face of the brand.
She walked around the streets of Manhattan in a pair of stone-coloured suede heeled boots.

Jennifer was also without her other beloved accompaniment, her boyfriend Justin Theroux, with whom the actress has barely been apart from in the last few weeks.
The couple have had a busy week, while Jennifer has been promoting her labour of love film, Five.
The 40-year-old actor waited in the wings while his A-list lady walked the red carpet at Skylight Soho in New York City on Monday to promote the movie.

Hand-in-hand: Jennifer looks happier than ever with her actor beau

Although he shyly refused to steal her limelight by posing together, he did show off her influence: the power couple were dressed in identical black outfits.
The sultry blonde star wore wide-leg trousers and a vest with nothing but a lacy black bra peeping out underneath and she finished off the ensemble with a simple gold necklace and black heels.
The Rock of Ages actor looked like a rocker in his typical outfit of black jeans, leather jacket and dress shoes.
Joining Jen at the event were fellow famous ladies Demi Moore, 48, and Alicia Keys, 30.
Project Five is Aniston's second foray into the world of directing.

She first sat in the director's chair for 2006 movie Room 10, a romantic drama based in the emergency room of a hospital.
Co-directed in partnership with her friend Andrea Buchanan, Room 10 won a jury prize at the Cinevegas Film Festival in Las Vegas.
Her next step is to direct and star in a full-length feature called The Goree Girls.

The film is based on a true story about eight women who were incarcerated at Texas’ Goree State Farm penitentiary in the 1940s.
The prisoners formed one of the first all-female western acts in history, capturing the hearts of millions in the process.
Project Five will air on the Lifetime Channel on October 10.
