After School Nana is a gem indeed that's why it's just understandable for advertising agencies to keep her as their muse.

In her recent instagram update, Nana shares a behind-the-scene preview of her new pictorial for cosmetic brand DHC Korea, which she has been endorsing for since last year.

In the photo, Nana is posing sexily wearing only skimpy yellow outfit. Her body curve is impressive to the fact that it's unedited. Her defined S-line is mind-flowing as well as her body proportions. Netizens are right when they said Nana's pictorial photos don't need retouched or photoshop.
