Go the glitter way.
A really simple design that just looks lovely at Christmas.
Start with a deep red, mine is a BOURJOIS from Boots. Once it is dry add a clear top coat and sprinkle with a glitter.
I have used Andrea Fulerton from Superdrugs. It is a holographic silver and come in a tube you can squeeze to get a nice effect across the body of the nail.
Simple but festive...
