Kim Kardashian suffered a wardrobe malfunction on an outing with her boyfriend Kanye West on Wednesday.

The expecting parents were dressed chic in all black in New York City and when paparazzi took close-up photos of Kardashian's dress, the lights from their cameras' revealed that the reality star's short black dress is transparent with sheer lining. The dress' fabric is so sheer it exposed her rear and underwear.

West, 35, and Kardashian, 32, reunited for the first time since Easter Sunday in Paris. West has been living there for several months working on his upcoming album.

The Kourtney & Kim Take Mimi star stepped out in New York City on Monday to attend E!'s upfronts with her mother, Kris Jenner, and her sister, Kourtney Kardashian. The couple reunited a few days after her divorce was finalized from Kris Humphries on April 19. The reality star revealed in an interview that she would like to marry West.

"I do think I would get married again," Kim told Seacrest in the E! special Ryan Seacrest With the Kardashians: An E! News Presentation, which aired on April 21.

TMZ reported that while it appears that West has not been spending time with Kim ever since they announced her pregnancy in late December, the Watch The Throne rapper has spent almost $100,000 in traveling abroad back and forth between Paris and Los Angeles to attend his girlfriend's prenatal appointments.

Sources told the gossip site that he has made at least three trips on private jet planes, has flown Kim out to Paris to see him and that he is in communication with her medical doctors for scheduling purposes.
