Men's gowns

Contrary to popular belief in parts of the western world, skirted garments are not exclusively reserved for women.

In the real world
Men in some cultures and subcultures traditionally wear shirts that fall between the calf and the ankle. In fact, wearing long, loose clothing to reflect the sun while allowing air to circulate was the only way that Cracked's Chris Bucholz found to beat the summer heat. But though it superficially resembles a "dress", it isn't women's clothing, despite what some members of the U.S. armed forces think.

In other fiction
Some well-known fictional men and boys wear shirts that fall past the calf.
 * Professor Albus Dumbledore, headmaster of Hogwarts from Harry Potter
 * Mickey Dugan from The Yellow Kid, without whom there would be no yellow journalism
 * John Darling from Peter Pan
 * Simon Seville from The Chipmunk Adventure, whose shirt a Cracked columnist calls "dress-like"; others agree, though Alvin apparently doesn't. "Looking into Alvin's eyes is like looking into a vat of powerful acid, perhaps sulfuric." Even after the 2007 reboot they still don't wear pants.
 * Intramural pillow fighting uniform at Plumfield Estate School from Louisa May Alcott's 1871 novel Little Men. (A real pillow fighting league doesn't use that uniform, however. )
