I used 1 coat of Milani Hi Res over 1 coat of Rimmel London Perfect Plum. I wanted it to be completely opaque and also use less of the Milani to achieve this.
Hi Res is such a soft and dreamy purple. The rainbow of colours (red, green, gold and blue) in all their holo goodness add to that fairytale feel it has. I love it! This one is definitely a keeper for me and the price is amazing ($3.99) considering how good the formula and the overall polish is.
