Eli5: Could someone please explain how bra sizing works?
In: Other
Bra sizing is *wonderfully* imprecise.
The standard American way:
You measure your “under bust” (where a bra’s band sits) snugly. That’s your band. Round up if odd.
You measure your bust at the fullest point, then minus the band size from it. Every 1″ of difference is a cup size. (0 AA 1″A 2″B ect.)
However, you really should measure your lying bust and leaning bust too. As breasts are not all super perky bolt ons so you can have larger breasts than just the bust measurement is saying.
That’s the *easy* part.
Cup sizes is essentially an estimated volume, but breasts come in different roots (width of base where it “attaches” to the body) and projection (how much it sticks out in a sillote). Bras are built to accommodate different roots and projections but *are not labeled for WHAT*. A woman with a wide root and shallow projection can have DD breasts on paper but not fill out a typical DD bra and it looks goofy due to the cup being more Mellon shaped than bowl. She would need to hunt for a more bowl shaped bra.
Now you know why the “women wears bra that fits perfectly but is so worn it should be shoot” meme exists, because if you are remotely not average shaped bras will be a pain in the ass.
