Who is this Cinderella looking for her shoes?

SNSD's Seohyun shared a very interesting photo of herself on her twitter account on November 27.
She tweeted, "what am i doing?where's my shoes?kekeke" along with the attached photo of her standing barefooted.

Wearing her white dress, which she had worn on MAMA 2013 during the acceptance of their 'Best Female Group Award', Seohyun looks like she doesn't need to wear high-heeled shoes to appear taller as her white shoes were just put next to her.

Apparently, fans assumed that the photo was taken during Hyoyeon and Seohyun's pictorial after the awarding ceremony. The photos were posted on their official Facebook account.

Fans commented, "Isn't she standing with Hyoyeon in this photo?","Maybe she was asked to take off her shoes so she won't appear taller than Hyoyeon, so cute.","She doesn't need it. She's tall enough."

What do you think could be the reason?
