Tiffany from Will Work for Makeup has a really great makeup blog imo; her latest post comparing Wet n’ Wild to Nars is really helpful! Would you have ever have guessed that the Pleasures of Paris palette from Nars was so similar to the Wet n Wild eyeshadow trio in Walking on Eggshell? Check out her swatches (and her general blog) here.
