They sure seem disporportinate to the numbers.

Yup... The 92 is smaller than the 88 >_>

They aren't giving the cup sizes. The upper-left one is labeled as 爆 (baku), which is the largest boob category in Japanese (that I know of), that's why I suppose she has the largest cup size.

as always, titless is better

86cm smaller than 79cm
and 72cm didn't need to wear any bra while 68cm needs it
hahahah...
