Many fans usually know f(x)'s Amber for her distinctive look. However, her recent selcas proved that the idol looks just as stunning with a long hairdo!

The idol tweeted the picture on July 12th, adding: "thanks for the make over u guy...." The message was later found to be directed at miss A's Fei, Min, and Jia who are known to be some of Amber's closest friends.

Amber is smiling playfully with a side-braid hair piece placed neatly on her left shoulder, giving off a cute and girly feel as compared to her tomboy image.

"This is the first time I've ever seen you with long hair, you should definitely grow it out!" comments one fan, "You look so pretty, you can definitely pull it off Amber."

Meanwhile, f(x) will be concluding their promotions for Electric Shock this week to ready their Japanese debut, expected to take place during the second half of the year.
