In the midst of intensifying battle of 'sexies' in K-pop with the return of numerous girl groups, the focal point among the competitors has been the legs, where the most exposure is tolerated on major TV networks.

Sistar has taken after the looks of 'Moulin Rouge' and returned as escort dancers on stage. With extremely short skirts with frills and corseted hot pants that show the entire length of their legs, Sistar has been at the center of the incoming summer wave of 'sexy.'

After School had a secret weapon up their sleeves: pole dancing. With skilled choreography using stage poles, After School succeeded in becoming a hot issue instantly upon their comeback. Short tops that reveal their toned midriffs definitely helped their cause, to say the least.

Dal Shabet, which has previously been a 'cute' girl group, said goodbye to their cute old days. Their best move in "Be Ambitious" is now dubbed the 'skirt-lifting dance,' a part of their performance that is self-explanatory. They have chosen Marilyn Monroe's sexy one-piece dress as their go-to outfits.
