#cup size

cup sizes... im what one might call a cup size connoisseur.... your average woman has between a C and E (in the usa, at least) so lets make D the standard. cup sizes progress through letters, so the smallest is A and the largest is Z. A is a 'flat chest', meanwhile people typically start thinking of E and above as a large bust.

some sizings will use doubles or triples of the same letter to go up a size, i.e a DD correlates to an E, a EEE correlates to G.

if you're trying to say 'character A has HUUUUGE tits. just absolute bazookas' you might say 'character A has a H cup.' essentially, the further you get from A in the alphabet, the larger the cup size will get.

sizes above K are extremely rare for non-overweight people without breast implants. the heavier set your character is, the bigger their baseline cup size might be.

if your character is the type to have breast implants, those typically increase cup size 1-3 sizes unless theyre big into the body mod scene and looking 'unnatural'.

band sizes are more straightforward, being the measurement around the ribs just below the bust. your average woman is somewhere between 30-50. as above, if someone is overweight their 'baseline' band size would be larger, and if someone is underweight it could be smaller. Although, actually, it wont change as much because the area around the ribs doesnt typically change size once you reach a certain low level of bodyfat. you'd need surgery to change that.

H cups in UK sizing, J cups in australian sizing, K cups in US/CA sizing, N cups in EU sizing....And they don't even make bras this big in Japan and France.
