This lovely necklace design/creation was taken from a great book called
"Bohemian Macramé" - Gwenael Petiot - Lark Jewelry & Beading.
It goes with lots of different outfits, can be worn at different lengths so would suit V or Round neck. Goes over the head with a simple sliding clasp to draw up to the desired length.
