This is a wonderful early example of a vintage Gottex swimsuit, dating most likely to the late 1950s.  It is a two piece bathing suit that is made with green and white horizontal stripes.  The top has a double button back closure and the bottom is made in a “boy shorts” style with solid green ties at the waist.  The top has a built in bra.  Gottex was a pioneer of swimsuits with hard-cup bras and the first to introduce spandex.
Label: Original Gottex Model.  Gottex was founded in Tel Aviv, Israel in 1956 by Lea Gottlieb who was the chief designer until 1998.  
Fabric:  No label, but this vintage Gottex swimsuitis made of some sort of synthetic knit, probably incorporated with spandex
