"Neck corset" manages to somehow sound more like an implement of strangulation than "choker." >_o
The actual piece, though, is definitely not torturous. The pearls are lovely accents. And while I can see a corset-looking clasp (?) in the front, it looks more like the gate to some grand estate. No one has been inside for a while, and the rose bushes are overtaking it in wonderful ways.
I think this type of necklace is called a Choker, not a Neck Corset. Semantics aside, I enjoy the design. The leafy branches give it an elegant feel with very little, which I like cause I think some chokers are a little too elaborate to be aesthetically pleasing to me.
