Chanel Riva Nail Lacquer ($27.00 for 0.4 fl. oz.) is a pale sky blue with ultra fine, barely-there iridescent blue shimmer strewn through the creamier, almost jelly-esque base. The swatches included in this post show the effect of three coats (and thicker ones at that)–I would say that you would need a muted white shade underneath, perhaps, or else four coats.
In all honesty, this is just not a shade to be worn opaque (at least not on its own). You’re better off wearing two coats and going for a sheer look than layering it on and ending up with a very thick pile o’ polish. I didn’t experience any streaking when applying the three coats, but it did seem more prone to bubbling (I don’t think I’ve ever really had a polish look like it was going to bubble on me… it was odd!).
I’m actually a big fan of Chanel’s polishes typically, but I can’t say I’m on the Riva bandwagon yet. The color itself is just not there for me; it lacks the dimensionality of other cult status Chanel shades–the shimmer is too fine, too soft, and it’s difficult to detect unless under direct, bright light. I had no idea this was a much anticipated shade until after I purchased it, which I’m glad for, because my expectations may have been even higher had I known.
Even more painful is the $4 price increase on Riva as compared to their other nail lacquers–what? I’m fully willing to pay $23 for a shade that only Chanel can do (or at least, is the first to do), but $27 for a shade with some application/formula issues and doesn’t quite hit the zing color-wise makes it impossible to recommend in good conscience!
