I agree with ABWG, you could benefit with some support! Ya, you may not be as big as a couple of us, but you are bigger then others!
One reason for visiting/joining this site was to reassure myself I wasn't jumping at shadows. Knowing something rationally is one thing, seeing it physically is another. I have decided it is due time to wear a bra. I would appear to be 46B from the measurement tables I have seen and they do indeed seem to provide a comfortable "fit". It is just a case of finding which style is best suited.
I see it as (in my own case at any rate) simply a function of advancing age. But I am equally well aware that the world in general is more judgemental than we as individuals might like, I have found throughout life that going with the flow gets one further than kicking against the traces. Others may find differently and if so good luck to them.
Seanodonovan, your breast shape and position is similar to mine. With wideset breasts, consider plunge style bras and wide gores since your breasts are not close together at the breast bone. They will be more comfortable than bras with close setting gores that will want to force the tissue toward the center to create cleavage unless you want to create cleavage. Make sure the band is firm, meaning it will be tighter than you might think, but not so tight it cuts off air or blood flow, but when you raise your arms the band should not move. I find that the firmer the band, the more comfortable the bra, which sounds wrong, but remember that the band gives 90% of support, not the straps. You want that bra to mold around your body, not hang off you body. The better molding, the more comfort as well as support. Also make sure the cups are the correct size meaning no quad boob or gaping space within the cup. The tissue should fill the cup nicely. I did a measurement and it said I wore one size, but when I tried on bras, I found that my band size was 4 inches smaller and the cups were 3 letters larger for proper fit. The measurement is a starting point, not an absolute. Be prepared to go down or up depending on your body. If you look at fitting videos, they usually say the biggest issue with women wearing the incorrect size bra is their actual size is smaller band and larger cups. I have seen many women say they would be wear something like a 36C and be totally miserable but when they were in their correct size, it was more like a 30G or H or 32F or G and they were very comfortable and well supported. And the numbers and letters are just not what size you are, they are for referencing cup size verses band size. A 34D is not the same cup volume as a 38D and that is how the sister sizes work. It is all about cup volume. Good luck.
