It's always seemed unfair that makeup and anything else considered "pretty" is off limits to men. There's a huge rift between the sexes, a whole world of unshared experience that it seems dudes are permanently barred from. But why, seriously? Guys would definitely be more attractive if they knew how to use a little concealer and eyeliner.
Plus, up until relatively recently, men were just as likely as women, if not more, to wear makeup and highly styled hair — just look at images from the French court in the 17th and 18th centuries. There's a long tradition of Casanovas who loved a good cream blush and cascades of curls, and it's odd that something most civilizations have treasured for everyone regardless of sex has become a preserve of just one, and an art that often gets knocked on at that.
