Girl group Nine Muses took their sexy concept to another level.

Nine Muses' agency Star Empire revealed recently that they changed their stage outfit from 'retro swimsuit look' to 'sporty look' concept for their song "Hurt Locker."

Nine Muses released their new mini album 9MUSES S/S EDITION on July 2- receiving much love.

"We wanted to look for something new as it's now the fourth week since their comeback. Then we decided to change the outfit to match their powerful dancing," said Star Empire.
