In the bottle they don't look like dupes. And for good reason, because they aren't exact dupes. Blue Lagoon is a shimmer, while WWTC? is a creme. The formula on both isn't difficult or bad, but when compared, the formula on the Revlon is smoother and goes on more evenly than OPI's pastel formula. OPI definitely wins me over with the Pro-Wide brush though- my nails are just the right size for that brush! Another difference is price- the OPI will set you back $8.50, while the Revlon is only $5.99. However, if you'd like to get your hands on this fraternal twin you should probably act quickly as it is limited edition.
But once you get them on the nail...
Pretty close, no? Now, you can obviously tell that WWTC? is a tad darker, and doesn't contain the same subtle shimmer that Blue Lagoon has. In person the color difference is much less noticeable- i had to take several pictures before the base even looked different. However, if you're lemming WWTC?, this could ease your craving until you can get your hands on the OPI.
Do you have either of these polishes, and do you think they're close enough to be referred to as similar? If you're looking for What's With The Cattitude?, could Blue Lagoon be a temporary substitute for your lemming? Thanks for reading!
