This is such a fun belt by Yves Saint Laurent from the 1970s. It is made of unique blue marbled lucite rings held together with silver hardware. It has two hook closures, so it can be worn long, or looped up as shown in the first two photos.

This belt can also be styled as a necklace, wrapped as many times as desired and hooked on any link!

Labeled YSL on silver tag

Excellent condition.
