For anyone wondering, the numbers in the upper-left-hand corner of the image refer to her bust and under-bust measurements respectively. I'm male, so I had no idea about any of this before I started researching what it could mean while translating, but if I have it right then an 86-67 should correspond to either an 8 DD or a 10 C bra size.
I'd sincerely like to stop developing sometime soon.
