Her long and thin eyebrows, water-like eyes, tall and beautiful nose, pink and soft lips, perfect curve of the convex in front of her chest, and in addition, her snow-like white skin. It really made people’s heart bump loudly. Even if it was said that she was a descended fairy, it would be correct.
Particularly jarring is the use of "convex" to describe her breasts. It was translated from the Chinese (so there's some translation problems):
My own translation of this would be:
Those slender eyelashes, those watery eyes, that tall nose, that pink tender small mouth, that bosom which protrudes like perfect arcs, and additionally with skin as white as snow. It really is beautiful enough to cause a person's heart to beat *peng peng* and say that she is a descended fairy.
I'm finding this tricky since 凸起 means "to protrude" and "convex", and the 的 indicates it's used as an adjective. Maybe I'm adding a nice spin on this, and it really does say "convex".
Question: How would we more accurately translate 那胸前凸起的完美弧度?
(I reiterate, this question is about accurately translating this phrase, not making it sound nice. What does it say? not What should it say?)
