As long as the rest of your look remains simple, you have nothing to fear, my dear. And by simple, we mean "accenting either the eyes or the mouth, and definitely in a neutral color scheme which accents natural coloring," B. explains.
Finish it all off with a simple pony tail or chignon, and you're ready for your cosmo.
Simple but Bold .. Southwestern Style at $32
The second picture here is a necklace that I just posted (on my Etsy Store) with this same color combination. It is a southwestern style necklace composed of turquoise and red beads with accents of silver. It is simple but makes a very BOLD statement at the same time.
The necklace is listed for only $32.00 and would be a compliment to any outfit. For more views, click on the picture.
