Yes, I think it closes in the front. I also thing the little curves that come up over the breasts are a separate piece, a fancy bra if you will.
A placket closure is likely how this goes together. Instead of the two pieces that meet front & center having hooks & eyes or buttons or whatever on their edges, the hooks & eyes are well inside (usually on the left as most people are right handed) on the body of the bodice and a placket. Sort of like a double breasted coat. This makes for a smoother closure, adds a bit more rigidity to the bodice as the placket itself is often boned, and a smoother profile to the whole bodice.
A placket is a flap of fabric that goes behind a closure. There is one inside every pair of jeans if you want to look at something for reference.
