Nana shocked netizens with her new short hairstyle.

Sportswear brand Barrel Co. announced Nana as their official endorsement model for their 'Life is Swell' swimsuit campaign earlier this year, and on July 10, Nana stunned at an event for the company in a simple light blue and white outdoor look and short hairstyle. As Nana has always been known for her long locks, netizens and fans were surprised to see her sporting such short hair, which gives her a completely different style.  

This isn't the first time the idol-turned-actress has surprised with a style transformation as she previously stunned many with her tattoos. 

Netizens commented, "Is that her real hair? Or a wig? She looks so pretty," "You look so pretty," "So pretty in your short hairstyle," and more.
