Oh yeah, I remember them doing Girl's Day's Expectation at some end of the year festival. Came off as cute anyway x) At least one girl seemed to do fine on that Weekl Idol ep!
They could try out more concepts that the regular innocent one even if they can't do sexy. I guess it's easier for SNSD members since they're older but they do a lot of varied concepts and a lot of them are just cool/chic or whatever you want to call it. Paparazzi was pretty hot but they could do a similar song with another outfit.
