Well, it is quite easy for a woman...
A little bit more difficult for a man.
Anyway, men can also do it. One man can do it, at least. But there are some requirements that men should follow:
#1 Be a close friend of Anna Wintour
#2 Have a character in South Park
#3 Have a tattoo of your South Park character
#4 Have a handsome brazilian boyfriend
#5 Have the name Jacobs, Marc Jacobs
It began with a kilt, a few years ago...
Yesterday evening, Marc Jacobs broke all the rules (well I don't think they exist at all!) and appeared wearing a polo shirt-dress at the Museé des Arts Décoratifes for a party that celebrated 15 years of Jacobs at Louis Vuitton.
Yes, he can!
