I'm sorry but I think they all have the same size.But I never knew that Sooyoung has the smallest.And Sunny and everyone else is the same.But if I HAD to pick Tiffany cause she is my bias.But still thinking the same
In my opinion : 1. Sunny 2. Jessica 3. Yuri 4. Seohyun 5.Tifanny 6.Hyoyeon 7.TaeYeon 8 / 9 : Sooyoung یا Yoona (IDK ) Sometimes Their's small and then bigger .. Maybe they are wearing some push up bra یا something stack in their bra so it will look bigger. lol
It's kind of obvious that Sunny has the biggest boobs and Sooyoung has the smallest. Jessica and Tiffany's boobs look like they're around the same size. Seohyun and Yuri's boobs are around the same size. Yoona's boobs look really small because she's really skinny, but I think her boobs are a similar size to Seohyun and Yuri's.
