Of course I had to buy a bottle, and when I got it home and on my nails, I found it wasn't really a shimmer but more of a foil and the color was a lot more pink-toned than I expected. It was nearly mannequin hands-y on my skintone—flashy mannequin hands, to be sure, but it blended with my coloring a lot more than I thought it would based on seeing the bottle in the store. I used three coats of this (no topcoat, as typical for swatches for me) but I might have been able to get away with two. Clean up was a challenge, as tiny flecks of silver got all over my skin and did not want to come off; quite festive, really.
Looking at the Whimisical bottle, it reminded me of another recent acquistion, Revlon Innocent from the Edgy Elegance collection.
On the nail, the Revlon has more of a rose pink tone compared to the L'Oreal's peachy pink, and it's not as foil-y. The Revlon has silver flecks in it, same as the L'Oreal, but in the Revlon, they create sort of a speckled look. I'm not sure what to call the Revlon's finish: foil shimmer, maybe? Whatever it is, I used two coats of it.
Neither of these look like fall colors to me, more like spring or even winter, but fall is when they showed up.
