Let me preface this by saying I am a man, and smoked a little too much, so I'm sitting here thinking... what is or was the original purpose of a bra? Weight support? Vanity? Covering the nips so people's eyes met your eyes and you can have a normal conversation? Like what's it all about?
Edit: context: a big part of it is weight support.
I’ve got a childhood friend who got a reduction because she had back problems after she went through puberty, and it basically led to her having chronic pain for a while in college. She’s WAY happier at a C-cup than whatever size she had before.
Edit: curious what the downvotes are for. This is absolutely a real thing. Downvoting me for sharing a thing that real people actually struggle with isn’t going to make them struggle with it less. And on the hunch that the downvotes are dudes: if you have a female partner, or a female friend who you can ask these sorts of things to, ask them to confirm that it is real, and they will be happy to.
You should probably tie it back into the actual question that OP had since I'm not sure everyone would make the connection between bras and what you wrote. I assume the other downvoters just hate the idea of a boob reduction.
Someone already mentioned that cup size has no meaning without band size, but also want to help dispel the myth that D is a “huge” size.
The rule of thumb is that your cup size is the difference between the size of your rib cage and the size around your chest. Then it’s 1” per cup, with caveats and adjustments, but we’re talking basics.
So in reality a C cup is a 3” difference between ribcage and breasts. That’s pretty modest. However in media, it’s often played up that DD is your Playboy model size, but those are more likely to be a G cup or larger, at least if they were sized correctly.
Yeah I am a certified member of the itty bitty committee and am currently in a perfectly fit 34D, and my measurements would put me in 32DD.
Those letters just don't really mean anything without the band size. Nobody, literally nobody, would look at me and think "D cup".
Bras really need more than two measurements. I need the band of a 32-34, the wire diameter dimensions of a 34D and the volume of what I think of as a 34 B. I can find this in particular models of bras but it would be nice to have it on the label.
