Out of all the members of girl groups, who has the best smile?

Recently in an online community, a bulletin post titled, "Female Girl Group Finalists with the Best Smiles." The post contained photos of KARA's Nicole, Secret's Hyosung and Girls' Generation's (SNSD) Tiffany.

The three idol group members, Nicole, Jeon Hyosung and Tiffany were famous for their killer smiles from the very beginning of their careers for "making people happy just by looking at their smiles."

People in the online community responded with comments like, "Don't forget Girl's Day's Minah", "There is Jung Eunji from A Pink", "Why isn't Sulli in the list?", "Tiffany is so pretty", "Hyosung has everything", "Wow, Hyosung has the best smile" and "Tiffany's smile seems like the best out of all the girl group members."

Finally, we ask our readers; Who has the best smile out of all the girl group members?
