Below: The sunlight fell on my nails in such a way that you can see it in both brighter and darker lighting.
Below: The shimmer in this one is very evident in any lighting really, and is such a pretty shade of cobalt or indigo blue against the darker teal base.
Below: I was curious what Chanel Illusion D'Or would look like over See You Soon, so I applied a coat before removing the Sinful. It turned the base into more of a dark green shade.
I'm loving this shade from Sinful! See You Soon is a black-based deep indigo shimmer with teal undertones. It reminds me quite a bit of one of my older and most loved Creative shades, NFS. The shimmer/micro glitter is a lighter shade of the base and is very sparkly and abundant. The application on this was perfect in 2 coats. I had just a touch of 'balding' on a few nails after the first coat, but the second coat covered everything just fine. The depth of this shade, combined with the color, beautiful shimmer, and of course the $1.99 price tag, make it a 'must have' in my opinion.
