.. There are no labels or stamps to indicate the maker of this amazing top.  It is certainly done in the Paco Rabanne style, but I cannot say for sure if it is, or is not a Rabanne original. 
.. This beautiful top was hand crafted with extraordinary detail.  The plates are made from either plastic or vinyl.  They are stiff with a slight flex, with a light texture.  The loops are silver metal jump rings.  The closures down the back are the spring loaded, slide in type so popular in the 1960s and 70s. Each plate seems to have been hand cut to formfit the body, as it fits like molded armor.  It even formfits to each breast... tres Barbarella!
