You could easily leave this at one coat as it applied very opaque and completely streak free :) This is shade DWS or concrete, neither of names are very appealing however I really love this colour and I don’t have anything remotely similar!
I’ve tried one or two other shades of gray but they always come out a bit too murky this one though is a pretty slate gray that looks like it almost has blue tinges to it in different lights
(left is in normal daylight the second is when it was really bright and sunny out)
I’m definitely going to be looking at more of Illamasqua’s nail polishes as although they are a lot more expensive (they're £13.50 from their online store however certain places do sell them for signifantly less!) than a lot of brands I want to see if others match DWS for consistency and finish!
