The year is off to a hot start, especially with all the exposure girl groups are bringing.

Girl groups are each going with sexy concepts, one after another. Male fans have nothing to complain about, especially with all their hearts aflutter. Girl's Day's "Something" was followed by Dal Shabet's "B.B.B. (Big Baby Baby)." And Rainbow's unit group Rainbow BLAXX has joined the girl group sexy war. Their dazzling 19 and over concept has the music industry buzzing.

Girl's Day put their emphasis on femininity. The agency stated, "They will be expressing a matured femininity from that seen in 'Expect' and 'Female President.' The members are all adults now, so their range of expression in song and dance have widened as well. Each one of the members will be showing off an upgraded femininity never seen before." In accord with their concept, they've increased the level of exposure, too. Before their official comeback leader Sojin revealed a see through cut of her whole body, which became a hot topic. On stage they performed wearing a tank top and a skirt with a long slit in the side. On top of that, they danced on the floor and even included choreography where they open and close their skirts, which added to the sexy feel of the song. As much as their exposure has increased, so has their popularity. "Something" is ranked in the top 3 across various music sites, and the music video on YouTube has surpassed 2,000,000 views. Girl's Day even won 1st place for 2 consecutive weeks on SBS' "Inkigayo."

Dal Shabet, on the other hand, focused on their 'lines,' or their figures. A rep from their agency Happy Face Entertainment commented, "This song doesn't have exposure." It was a declaration of determination to show Dal Shabet's advanced image even without exposing their bodies. All the members wore blazers and gave off a 'mannish' feel. They also wore form fitting leggings that accentuated their 'S lines' and showed off their sexiness that way. Their dance moves included the wave and pelvic dances, which highlighted their beautiful body lines more than give off a sensual feel.

Rainbow BLAXX came back with a twist. Before their comeback on the 20th, the members have been revealing 19 and over concept photos and videos ranging from voyeur shots to semi-nude bath scenes. With each photo or video release, Rainbow BLAXX ranked at the top of internet search queries, and has been showing increased popularity. A DSP Media rep stated, "They're a unit that started with the sexy image. We've put the emphasis on feminine beauty." The group is planning to bring back a twist with their music. Although they have an adult concept, they plan to surprise their fans with an exciting retro sound.

How should we look at the girl groups' sexy concept battle? A matter of influence in this matter relies heavily on the limitations of concepts. Except for the very few who choose a unique or original concept, girls groups seem to choose between either the cutie or sexy concept. For girl groups that haven't debuted too long ago, it seems as the popular choice is to go with the cutie concept. Then, 3-5 years into their activities, when the members all become adults, they all seem to naturally flow into the sexy concept. Even with so many teams, there are only a few concepts they choose from, so fierce competition between girl groups with same concepts are inevitable. Not only that, since there are so many sexy concept girl groups, the public's interests have dwindled. To be sure, they're still widely popular, just not as much so. And so girl groups strive to catch the public's attention with even more revealing attire, choreography, or concepts.

One source commented, "Honestly speaking the easiest concept for girl groups to show off is the sexy concept. That's because the sexy concept shows off the female sex. That's why so many girl groups are coming out with this concept. There are so many active groups, and the public is always looking for something new. In order to get noticed, the girl groups have to push the limits and bring forth a newer or stronger concept. They need to think of a new and powerful concept that can pique the senses."

Another source commented, "It all boils down to skill. It's true that taking off more clothes will help you become a greater issue. But there's a limit to body exposure, and noise-marketing is just a one-time thing. A singer must be victorious through singing. If you don't have talent you'll become a hot issue one day and disappear the next."
