As I was looking at Danni Ahe photos, I saw this one with Sarenna and it reminded me of this thread. 
From what I understand, Danni’s reported bra size around the time of this photo was 32FF, and given her height and frame etc, I’d suspect that’s about right (until recently, I was a 32FF - I’m now a 30GG - but her boobs are remarkably similar to mine).
With that in mind, it makes me wonder about Sarenna’s size. I think I’ve done an assessment on her before, but I’d suspect she’s up in the 32-34JJ/K category. She’s definitely bigger all round, both in height, frame and body size - and her boobs are 3-4 cup sizes bigger than Danni.
