So this blog is helping me learn a lot - which is great. I feel a little silly that I have never heard of a product that you could apply over top varnish that would give it that "matte" effect. How brilliant right? Silly Sarah...
Anyhoo - dedicated to Slaminsky - as requested.
£4.50 Rimmel London Pro Matte Top Coat
£10.95 Essie Matte About You
Pocket Burner (but probably awesome)
£18.25 O.P.I Matte Nail Envy Natural Nail Strength
All available from http://www.asos.com I heard the Number 7 from Boots version is good too but sold out online (that was my first choice - I decided to go with the Rimmel watch this space).
I found this blog as well quite helpful, great for colour swatches and she's got great nails!
