We all know how petite the Girls' Generation members are, but maybe Taeyeon is even smaller than we thought!

In the latest episode of Mnet's 'Heart Attack' (also known as 'Heart-A-Tag') MC Tiffany and Taeyeon were shopping for 'early summer must-have items'. 

Taeyeon was confident and having fun looking around until she was told, "Try this on." That's when Taeyeon burst out laughing. She called Tiffany and told her, "Everything is too long for me." Later on, she asked, "Are there any kid sizes?"

In the end, Taeyeon found a solution. She said, "I'll wear a long skirt and wear really high heels."
