Very nice. I've personally been hesitant of collars like that on dresses because they remind me too much of the stuffy button-downs and polo shirts I used to wear, but this could make me reconsider.
At some point you will probably want to take it off to wash it. What's it made out of?
Interesting perspective. But rayon, gah... I've got a couple rayon garments, but I never wear them because washing them is kind of a pain. I do it by hand, they get really heavy from soaking up so much water, and they take forever to air dry... maybe I'm doing it wrong lol
