A finish I don't tend to wear much. Why? Because it often looks brushstrokey and also, I don't much like the frosted/pearly look that can sometimes come off of metallics.
So, instead of a plain metallic I chose... Barry M Chameleon Blue!
It was opaque in one coat but I did two because it it showed just about every single ridge on my nails.
I wasn't feeling particularly creative so I just did dots...
I guess in the future I will wear topcoat anyway so I'm happy that I prefer the 'topcoat' colour.
