Bras has to fit fairly snug to function correctly and that requires some level of precision.
Eh, it can be argued that the “function” of a bra is to allow women to adhere to the beauty standards set for them by men.
That being said, they still aren’t made that precisely, cup sizes are kinda all over the place depending on brand, and even the band sizes (which are kinda sorta close to the actual inch measurement of your ribcage, but not quite) are variable. That’s why bras have adjustable straps everywhere, and why if you haven’t been professionally fitted for one, your bras probably don’t fit you right.
