For my post today I have a nail polish that I wore last week(I know bad blogging) it is Topshop Nail Polish in Mermaid(£6.00). When you look at the bottle it looks like it is a duochrome but it is not, it is a gorgeous colour though. It's a multi toned metallic silver blue with green undertones with fine gold shimmer. The name is actually perfect as it looks like a mermaids tail :)
The one bad things is as with most metallic polishes you can see brush marks so you do have to be careful.
Have you tried any Topshop polishes?What is your favourite colours?
