However, it wasn't just any dress. The long-sleeved, black gown was see-through, and as photographers snapped away, her nipple covers showed through.
"Joanna Krupa stepped out last [night] for the Humane Society of the United States 60th Anniversary party," Reality Tea reported on March 30. "The Real Housewives of Miami star gave the photographers a little more than they were expecting. Joanna's black and gold Michael Costello gown was see through!"
After walking the red carpet, the longtime model and star of Bravo's "The Real Housewives of Miami" took to Twitter where she told fans, "Omg I was just told by the paparazzi at HSUS 60 th anniversary that my @michaelcostello31 dress is see through! Does it in this pic?!!"
In the photo she posted, Krupa's nipple covers were seen as clear as day, and while many thought that it was her actual nipple which was seen, she confirmed that she was wearing covers -- which is a little odd considering she's gone out in sheer clothing with no bra or nipple covers in the past.
