I'm not sure if you can still find this polish but I was lucky enough to get it from K-Mart since it seems most people don't really shop there for makeup.
This is suposely the dupe for Deborah Lippmann's Glitter in the Air. From the swatches I've seen, they look pretty darn close. As far as application goes, I did struggle a little. Well, actually I did struggle a little more than little because it was very hard to pick up the glitters. I had to dip my brush several times in order to fish them out. The base is a milky, sheer, light blue and I think the colors of the glitters are just so cute. I spy some tiny pink and blue glitters also.
I think most people would prefer to layer this on top of another polish and I've tested few different shades and Whimsical is best paired with a light pastel base color.
I really like this polish, in spite of the application issue. It looks pretty and reminds me of sprinkles on cupcakes.
