OMG, I can honestly say that I had a hard time looking for this!!! I think I went to every drugstore around my job and my neighborhood, until I found the display at a Rite Aid by my son's daycare. They say that this is a cheap Dupe for "Chanel's Paradoxal" and it is very similar.
Perplex is a described as a purple with grey undertones and it's the perfect fall/winter color. My sister and niece saw my manicure and begged me to get them each one. Now I have to pray that I find at least 2 bottles again! lol
