Katie Holmes may be becoming the next fashion icon.

Jamie Foxx and Tom Cruise's ex was spotted out yesterday by the paparazzi, and she was showing some major cleavage while hailing a cab in Downtown Manhattan. 

The pics of Katie went viral - and ended up selling millions in fashion merchandise. Katie was wearing a sexy cashmere bra and matching sweater in "barley'' by Khaite.

According to the company, the ensemble sold out almost immediately after these photos of the newly single star were published. 

The 40-year-old actress was also wearing jeans, oversized sunglasses and a soft cashmere cardigan that was loosely clasped with only one button. The cardigan fell off her shoulder, revealing the slightest hint of a cashmere bra underneath. 

The look - which costs a whopping $520 - sold out in just an hour. Talk about impact.
