I just happened upon the NYC Matte Me Crazy mattifying top coat in the store today, and I got so excited, I didn't even bother changing my polish before trying it out. The mani I had on is this one with two coats of Pure Ice in Rio on top and no topcoat.
To best show this top coat off I have a picture of the original mani:
And a picture of it with NYC Extra Shiny Top Coat on the pinkie and Matte Me Crazy on the index finger and the other nails as they were:
It did what it was supposed to do, and that makes me happy. Plus it has good dry time. Pink Wednesday is definitely going matte this week.
