Below: Don't give up on it yet though! Layer one coat over almost any other polish, and you'll be entertained for hours playing around with the possibilities. Here it is over China Glaze Midnight Ride (deep purple shimmer). Apologies in advance for the messy job I did, but you get the idea!
Above & Below: This is shown under an Ott light with no flash, while below is with a flash.
Below: This Sinful polish actually creates a duo chrome look, as you can see purple and green flashes in different lighting, which is more intense than I was able to capture in these photos.
Below: Apologies again for the mess, as I have several layers on by now! Here is one coat of the Sinful over China Glaze Blue Sparrow. Although not as duo chromatic over this shade as it is above, it's still quite interesting how it transforms itself. It adds a golden veil of shimmer, and a very subtle green flash.
Above & Below: The photo above shows green and gold shimmer when using a flash, while the photos below show the gold veil and slight duo chrome a little better.
Sinful You Just Wait is a very sheer pink shimmer with pale gold highlights...nothing special and in my opinion, almost too sheer to be worn alone. But used as a top coat, this is quite the performer for $1.99! In the bottle it appears to be a shell pink with a slight foil look and an even slighter light green flash. I used it over 2 other shades as you see in the photos, and although it tends to always pull a bit of green, it does look and act differently, depending on what you layer it over. I love these cheap drugstore polishes that don't look like anything special, but then have duo purposes--and a duo chrome look!
