I don't think this is OF - forgive me if it is.
My guess is 30J - and what a well fitting brassiere it is.
Margaret it is over to you...
Okay, lady number two…
Despite how it looks, that’s not an especially well-fitting bra….
Do you notice how the centre gore in between the cups isn’t sitting flush with her sternum? Normally, that indicates (to me, and other people who know bras) that she needs to go up a cup size. Although, her boobs are encased decently in the cups, which is a good sign.
However, from what I can tell, her back band is riding up a little - just as it curves under her armpit. That (along with the centre gore not sitting flush) tells me she’s needing to go up a band size - at least.
Now, in terms of bra size - I’ve looked around and found other more recent photos of this particularly beautiful lady, and I suspect she is slightly taller than average - probably about 5’7”. And, she has pretty big volume in her breast tissue now - so 30J isn’t a million miles away from what she might be, but given that she has a slightly broader back, I’m thinking possibly she needs a 30JJ or a 32J.
I’m going to say 32J, but she could easily also be a 32H/HH too.
I’d love to know what bra size she’s wearing in this photo!
