Simple, classy nails are where it's at for men. While women love trying fun nail designs, most guys think it's a tacky if you have nails covered in hearts or palm trees. Try a shade like Passion by OPI, all the rage at New York Fall 2012 Fashion Week, which you may have heard is going on right now. Also, MAC Cosmetics is customizing nail colors for a bunch of designers, like Zac Posen, for Fashion Week this year, so you should check their colors out, too. They have great matte shades.
