Gender Bender styles: Is it acceptable nowadays?

I don't know what is it nowadays in the menswear department that some 'gender bender' styles seems to flock in. On my way to college last friday, I saw this guy clinging a Mulberry Piccadilly bag that is supposedly for the ladies. And also, recently in some of the blogs saw Marc Jacobs sports a 'skirt' on his way to the office. What happens to guys these days? Are they out of their mind? Or is it a new age of fashion statement that they wanna shout out?

The term gender bender is normally used when an item of clothing from other gender is used by the other gender. Say, a skirt which normally used by the ladies is now used by men. I know that gender bender style is not new. Sometimes it is undefined, whether it is for men or for women. For example, tartan kilts are famously used by the Scotts' men. Also, the Asians in the like of Indians, Malay, Cambodian and Burmese also make the wearing of sarong so popular. The wearing of tunic is also popular among the Arabs, Persian and Indians, which saw the term salwar kameez being used in many literatures.

For me I think gender bender style is acceptable within limit. As long as a guy don't wear evening dress (like in the yesteryear's Versace ad)... or hot pants, or any item of clothing is surely for women, then it doesn't really matter.
