In the picture, I used a colorful, large vintage earring, but a vintage shoe clip would work as well, or you could use a brooch as the pendant. When using a brooch as the pendant in this style, you may need to knot the scarf in the middle so that you can pin it securely. To complete the scarf necklace, simply tie the ends together in the back.
This style doesn't necessarily have to be worn with a V-neckline. It's a pendant necklace, so it will create its own V-shape, which is flattering for short women.
