Concepts are a huge deal when it comes to K-pop, and fashion plays a huge role in that as well. Many K-pop groups attempt to look uniform, and a big girl crush concept has been girl groups pulling off suit-fit looks in their performances and concepts.

The suit fits not only look fire, but they also illustrate a girl-crush concept, and they honestly all look so sleek with the concept as well. Some girl groups can completely manifest this concept, and today - we'll be taking a look at some girl group concepts that have been absolutely killing it with their suit-fit looks. So whether that be through performance or through a music video, let's take a look below! 

TWICE - Scientist

While promoting "Scientist," the ladies of TWICE completely killed the suit-fit look and showed a more mature side of themselves. They would be GREAT as corporate folks! 

ITZY - LOCO

ITZY showcased a performance of "LOCO" through a suit fit, that showed that they were fire and pretty at the same time, and fans definitely wanted to see more suit fits from ITZY.

WSJN The Black - Easy

Oh My Girl - Dun Dun Dance

In contrast to the actual song, Oh My Girl performed "Dun Dun Dance" (and yes -- it's a bright song) with a suit fit, and they absolutely killed it! Fans were so delighted to see the mature look that somehow made it work with the cheerful song.

STAYC - So Bad

STAYC performed "So Bad" on only their second day of debut with their debut song "So Bad," and it has remained as one of their most legendary performances of the song!

Veterans A PINK performed their hit song "Dumdurum," displaying their charisma and maturity in suit looks, showing their true veteran side!
