Girls' Generation's YoonA proved herself to be the nation's sweetheart once again with a very girly and lovely photo shoot with 'Sure' magazine for its August issue, even landing the cover with her cheerful and signature smile.

Rather than focusing on looking chic or serious, she was her natural, comfortable self, saying she liked how the pictures portrayed a normal, everyday life as she thoroughly monitored herself throughout the shoot.

Which is your favorite shot?
