I've heard a lot of hype lately about Revlon Wintermint being a dupe for Deborah Lippmann Mermaid's Dream. I figured since I have both, why not compare them! Of course Wintermint gets a few extra points from me because it smells so good.
At first sight its pretty clear that Revlon has a lot less dark blue metallic glitter. The base colors are similar, Wintermint is a touch lighter, but less sheer than Mermaid's Dream. It also looks like Mermaid's Dream has a lot more shimmer than Wintermint. If you're going for overall look, I'd go with Mermaid's Dream, but if you love scented polish than its definitely Wintermint!
