After modeling the 'natural summer resort look' for the magazine, Sooyoung sat down for an interview where she was asked about her dieting method.
Sooyoung said, "I've been getting a lot of questions about my dieting method lately. I guess I look better because I've gained weight. I was really skinny before. I think building muscular strength through yoga and PT helped."
