I own Out To Shock, and coincidentally, I wore it today layered with Vivacious. Anyhoo, I've only seen swatches online of Saint Germain, so I'm not sure if it's really a dupe. I'm sure it's not as light as Out To Shock ...but it seems close?? Maybe someone else who actually has seen Saint Germain in person can confirm yay or nay?? HTH
