"T157cm B100(I) W58 H88" I have no clue what the T is. However, B 100 means she has a 39 inch bustline, and if the I works the same as western measurements, means that her cup size is 9 cm more than that (a D cup is 4 inches over the line under the bust), which is equivalent to, well, a D cup. So a Japanese 100I = an American 38D, give or take. But the 157 is definitely not her circumference at the breasts. I have no clue what the T is.
