Simple and fairly inexpensive DIY.
take some chain then weave a skinny piece of fabric through it. You could do this with silver or gold chain and use any type of fabric you want. This DIY is very customizable. You could make one that goes with pretty much everything, or you could make a statement piece. I'd advise to not use fabric that frays easily (like satin) unless you are going for that look. You could also just use ribbon as well.
