I was going through polishes, trying to organize some of the chaos. Sort of prepping for the new organizer I'll be getting (i'm sure i'll have a before and after post for that) Anyhow, I noticed that I had a Sinful Colors polish that at first glance looked an awful lot like Water You Waiting For... So, I snapped some pics, did a couple swatches on a color wheel, and here are the results.
SO, it's not a "dupe" but man it was close. I hate when I get home with a new polish only to find that I have one that's basically the same thing already. :)
