Don’t be afraid of color! If your favorite color is blue, buy earrings with blue gemstones. Jewelry does not have to be neutral. Buy color. I wear my colored gemstone earrings with whatever color of clothing I have on.
I will wear yellow with amethyst earrings. Believe me, you can make color work. If your clothes are neutral, your gemstone earrings, necklace, rings can provide the pop of color along with your lipstick.
