4minute's HyunA has become a hot issue regarding her outfit, with photos of her taken at a recent World Cup open concert in Seoul making its' way online. The 4minute girls had attended a recent street cheering concert in order to show their support for Korea by performing their recent hit songs on the 17th before the Korea Republic vs Argentina game. Some fans who attended the concert later commented about her clothing attire online, by saying that she was showing excessive amounts of skin. HyunA quickly defended herself by taking part in an interview held at the MBC Dream Center where she expressed the following,

"Singers should be able to choose the costumes they want to wear while performing. Fashion is popular all around the world, but in Korea, fashion is more strict due to the conservative culture. Many things I wear are somehow tied into a controversy, and that's very disappointing. I just want to show my true self on stage, and tying in my costume with the performance."
