The Yin Yang symbol is the Chinese principle that all things exist as inseparable and as contradictory opposites. That two opposites attract and complement each other—neither is superior to the other and, as one increases, the other decreases but there is always hope of harmony. Children of the 90s also might have a special place in their heart for this collection—most of us were not particularly concerned with the forces that join the universe—we were more interested in wearing whatever Claire’s was selling or what Cher Horowitz was wearing. We’re feelin’ a 90s-revival making its way into all of our lives.
