One thing that I seem to spend so much of my spare time doing (apart from looking on the Internet) is painting my nails. I always find that I need some sort of colour on them, even a nude will do, otherwise I feel undressed and I have missed something.
I have my a go to red, that I love and can rely on to go with anything, but I also like to mix it up and try different colours.
One of my favorite nudes is Essie's 'Topless & Barefoot' it works really well with my skin tone and doesn't look like it blends into my skin. To add a bit of sparkle, I created an accent nail (on my ring finger) using Nails Inc's 'Victoria Embankment'.
