MAMAMOO's Hwa Sa and Hyorin opened up about their viral outfits. 

Hwa Sa became a hot issue for the hot red body suit she wore at the '2018 MAMA.' Hyorin also made headlines for the glittery one-piece suit she wore at the '2018 KBS Drama Awards.' 

On the January 30 airing of MBC's 'Radio Star,' Hwa Sa and Hyorin share their reactions to the issue. 

Hyorin stated the attention on her outfit was totally unexpected. The only thought she had after her performance was regret on her dissatisfying vocals. She also explained the outfit was handmade by a designer. She said, "I purchased the outfit because I wanted to wear it at my first solo concert. I just wanted to wear the coolest, and the most luxurious outfit I have."

Next, Hwa Sa revealed she requested the outfit herself to the stylist but the stylist actually opposed. She explained, "I never tend to think I'm overdoing it. I just think it's part of the performance but my peers tell me it's too much and controls for me."

When asked, "Which part did they think was too much?" Hwa Sa replied, "I guess the part where the butt is exposed? But I believe I shouldn't wear it at all if it's going to be iffy." She added, "I care more about how I can look cooler stage rather than what I'm wearing."
