Kim Kardashian is back in black!

On Tuesday, the pregnant reality star stepped out in NYC wearing all black, and exposing her cleavage in a sexy see-through bra top. Now that Labor Day's done and gone it seems as though the reality has faded back to black -- which is a look we know she loves.

The 34-year-old has been carting around her two-year-old daughter Nori all around the Big Apple during her trip. The on-the-go mom has had business meetings and plenty to keep her busy during her trip to the East Coast.

The superstar is definitely changing up her maternity garb these days. On Monday night, Kimmy K donned Kanye's vintage Ramones t-shirt for a dinner with Serena Williams.

Last night may have been all about hanging with a gal pal, but today was all about family. The Kardashian met up with her model sister Kendall, who was showing a whole lotta thigh! Both girls were all about the black as they headed into the studio in NYC.
