Popular rookie girl group G-Friend, much loved for their sweet image, recently posed for the April issue of 'CeCi,' keeping in tune with their lovely concept by dolling up in cute sailor-themed outfits.

The refreshing denim one-pieces, the matching tones of blue-and-white and black-and-white, and their girl-next-door looks including high ponytails have them looking the perfect "girlfriends" as their name implies.  Their youthfulness is especially appealing as they look energetic and innocent with their average age being 18.1 years old.  

In the interview, Yerin, who showed off her quirky personality on 'Running Man' recently, stated, "I endured the difficult practice by imagining myself on stage.  We will work hard to be known as the nation's girlfriend from hereon.  Please remember me as the eternally bright and positive child."

Main vocalist Yuju said regarding G-Friend's competitive edge, "The balance between a choreography that pushes the body to the limit and a femininity," and asked people to view pretty the members' frisky and playful nature like beagles that are hard to hide, promising repayment in the form of good music and performances.  Leader Sowon said that she always wanted to show constant development.
