That is designer Rudi Gernreich's famous Monokini, as linked by MrDorkESQ. [He generally had some interesting ideas about women's fashion](http://en.wikipedia.org/wiki/Rudi_Gernreich) and created the basis for many of the modern bra designs you see today.
LIFE? Must be a European edition.
Cute swimsuit- maybe it will come back in style one day...
