Some netizens have been spotted that Nana and Katy Perry were wearing the almost same outfits last year. But if you look clearer, you can see that it is actually a little bit different. Probably one of them redesigned the dress.

On the left side is Katy Perry at Victoria's Secret Fashion Show 2010. On the right is Nana wearing it at the year end show SBS Gayo Daejun 2010 along with Raina and Lizzy as shown below. So which one do you prefer, the Korea or the U.S ones? Share your thought!
