After some random swatch googling, my narrow mind was exposed to the existence of matte nail polish, so I decided to jump on the band wagon asap! Here I've used Rimmel matte top coat over la femme ebony and no.7 in vivid violet over that.
I found the actually texture of the nail quite intriguing, I really expected it to feel kind of chalky, but it's actually very smooth and satiny.
Also did some contrasting shiny French tips, using a clear top coat as a bit of an experiment, and I actually really like it, I reckon you could have a lot of fun doing contrasting shiny/matte nail art.
I have to say though, they really remind me of a Cadbury Wrapper, particularly the flash pic!
