I was actually pretty surprised by this because Twice has had very lax standards for their members' weights over the last few years, so I dug up the performance where this photo was taken.twice’s sana is looking really good these days. i knew she must be getting skinny when people started complaining about it on twitter.

I think this is probably the best she's looked (body wise, at least) in recent memory. Hopefully, she'll keep losing, but I wouldn't be surprised if this is another situation like Sunmi with Gashina, where an idol is super skinny for one comeback and then returns to her usual weight.
