They're the sexiest girl group in K-pop, famous for their healthy curves and beautiful bodies, so it's no wonder that Sistar are confident in their appearance.
During a June 29 group appearance on SBS Power FM's Old School show, the members candidly discussed body image and weight truths with host Kim Chang Ryul.
Soyou, 23, admitted that, despite struggles in the past, she's confident with her body. "I rarely dislike my body," she said during the show's "Break Time" segment.
"[But] depending on the season, I think I'm kind of envious [of the other members]... In spring and winter, I want a delicate body like Dasom's. In the summer, it's always Hyorin-unnie."
"I'm slightly envious of Bora-unnie in the winter. I think that a body like Bora-unnie's is the only kind that looks good sweater on."
When Kim asked Hyorin, 24, what was the most she ever weighed, she refused to answer.
But she revealed, "I can't say. I probably weighed the most. Even now, I weigh the most among the four of us."

Bora, 25, added, "She's the shortest among us, so I think she's trying to say she weighs more for her height." And Soyou even explained, "I think Hyolyn-unnie's face looks good when she gains weight. Her face looks gentler."
