If you follow me on Youtube, I mentioned that Groupie could be a dupe for OPI's Grape...Set...Match. I swatched the two side by side and noticed that they are NOT the same. From the bottle they look the same, but once swatched, Groupie has purple glitters in it while Grape...Set...Match has an array of colors for glitter. Nonetheless, I'm loving this polish. It certainly has that rock star feel to it.
