I did my friend's nails a while back:
We agreed on pink with black and silver and I decided on a tape mani :) So after basecoat, I applied 2 coats of Catrice "Pinky and the Brain". Then one coat of Seche, to speed up the drying process. Then I taped of her tips asymmetrically and applied the silver. Then again with Seche and tape and black. To top it off, one more coat of Seche and voilà!
