I see a lot of women on here revealing breast sizes, usually in the same way that bra sizes are measured. The part that's confusing me is that I keep seeing breasts described as 48DD or 84EE or 48D etc. My impression was that the first number was band size-- the measurement of your ribcage under your breasts. The cup size is what actually indicates the size of the breasts independent of the band size. So, for example, a woman with a 40C bra size would have approximately the same size breasts as a woman with a 36C or a 42C. Likewise, a woman with a 40C would have the same measurement under the breasts as a 42C, 36C, etc. which in general indicates stature. I'm not trying to be snide at all, but I've seen this here and elsewhere. When people post their breast sizes, are they not using bra sizes but instead measuring around the fullest part of the breast for the first number, then the cup size? I normally report my breast size as 38D because that's what my bra size is. Or at least, that's what I think it is. Is there another convention where I'd be a 42D because 42 is the full measurement around my entire bust? Also, when people report their measurements, i.e. 36-24-36, is that first number around the full bust or under? I think it's around. I've been measuring for new bras since the old ones don't fit anymore, and I can never get a proper freakin measurement, and I started thinking about this. Acoording to one of the sizing charts online, I'm a 42A. According to another, I'm a 36DD. Huh? This is a cool site about bra fit, the one that told me I'm a 36DD: Intimacy, The Bra Fit Specialist - Prima Donna, Chantelle, Aubade, and More! Now this site says I'm a 40D: Bra Size Calculator Anyway, I'm completely confused. Any of you ladies have any ideas about any of this?
