Here's what I did. I did 6 different mustaches, 3 on each nail, along with stripes on the thumbs and dots on the pinkies. I chose to put the mustaches sideways so I could be silly and use them as fake mustaches, hehe.

3 coats of Revlon Minted
I drew the mustaches and dots with Sinful Colors Black on Black and use Sinful Colors Time Off stripper for the black lines.
