Recently on an online community board, a picture of Seohyun's growth from when she was younger to now was posted.
There were many different pictures of her from being an MC to casual outings.
Internet users commented, "Her body is like a barbie" and "Even though she is the youngest, her body is mature."
Girls' Generation's 6th Japanese single, Flower Power, will be released on November 14.
