I have a soft spot for simple yet creative, unique accessories. I think I can pull this off if I pair it with a bone-coloured tank top:
Mono_Clothing - Bone Leather Knotted Necklace (USD277.00)
A bit on the pricey side but then again, you can't really put a price on a statement piece.
Find it at: http://www.notjustalabel.com (one of my favourite online stores and a truly one-of-kind place to shop).
