Girl's Day changed up their "Hug Me Once" stage outfits from a wedding look to a "Mathilda-look", as inspired by the popular French film, 'Leon: The Professional'. Girl's Day showed off their new Mathilda-inspired outfits on the July 21st broadcast of Mnet's 'M! Countdown'. A representative revealed,

"Girl's Day will be changing their outfits from the symbolically innocent wedding dresses to an interpretation of a Mathilda look that emphasizes their cuteness. The Mathilda look was taken from the movie 'Leon: The Professional'. We anticipate that it will bring forth the feeling of a cool and lively summer girl. The Mathilda style point is the pendant choker and striped shirt. They will be showing an overall punky look with high-waisted pants and skirts."
