The second of the OPI Gwen Stefani range that I bought was 4 in the Morning, a matte black.
This is two coats, no topcoat.
I love the finish on this - it's a smooth, satiny chalkboard kind of black, which I really like. The application is lovely - it's a really nice formula, and I didn't do any clean up at all, which is almost unheard of for me with OPI brushes, which are usually too wide for my nails.
I then added some Barry M Pink Foil on the undersides of my nails - this is my new favourite way of jazzing up a look, now that my nails are getting so long. I love this pink, and this effect. It's very hard to photograph though!
