I wore these colours recently and I liked the effect!
First of all, I have been using OPI's nail envy which is a nail strengthener/treatment.
Me likes. It makes a great nail polish base. Seriously. Polish just applies way better over it.
2 coats of OPI nail envy
2 coats of Revlon Silver Coin
1 coat of OPI Glitzerland
1 coat of Seche Vite top coat
The result is a sort of duocrome mixed metal nail!
