How did kilts become accepted as men's attire?

Answer 1

The first answer sums most of it up. Pants (trousers, slacks, whatever you call them) are the new thing (very knew in the history of clothing). All around the world the original bottoms were kilts, robes, sarongs, and so on.

I once read something that said were you to show a picture of a naked man a picture of a naked woman, a picture of pants and a picture of a skirt/dress to aliens or someone who knew nothing about human cultures, they'd probably put the man in the skirt...why? Look what's between the legs, who needs a little more space down there?

The Kilt itself developed in Scottland over many years due to a combination of materials available, cloth weaving techniques that developed, dyes available and eventually the use of different patterns (tartans) to distunguish between different groups and families (clans). It should be noted that a type of kilt also developed in Ireland (considering the close ties between the galic and celtic cultures this should be no suprise) however this was abandoned long ago.

Scots may have aboandoned it to except in the 1700's England tried to forbid Scots from wearing tartans and kilts in an attempt to make them forget their heritage and step in line with the English rule. Several other Scottish item were outlawed but it was the forbidding of the tartan that really riled up the Scots. Instead the Scots fought back and to this day PROUDLY wear their family tartans and the kilt.

Answer 2

the better question is how did pants...?

men used to wear robes. i am not sure how it changed to pants.

here you go: http://en.wikipedia.org/wiki/History_of_the_kilt

how pants came to be:
"Nomadic Eurasian horsemen/women such as the Iranian Scythians, along with Achaemenid Persians were among the first to wear trousers, later introduced to modern Europe via either the Hungarians or Ottoman Turks. However, the Celts also seem to have worn them in ancient Europe. [citation needed]

In ancient China, trousers were only worn by cavalry. According to tradition, they were first introduced by King Wu of Zhao in 375 BC, who copied the custom from non-Chinese horsemen on his northern border.

Trousers were introduced into Western European culture at several points in history, but gained their current predominance only in the 16th century.

The word itself is of Gaelic origin, from the Middle Irish word "triubhas" (close-fitting shorts).

[edit] Men's trousers

Trousers also trace their ancestry to the individual hose worn by men in the 15th century (which is why trousers are plural and not singular). The hose were easy to make and fastened to a doublet at the top with ties called "points", but as time went by, the two hose were joined, first in the back then across the front, but still leaving a large opening for sanitary functions. Originally, doublets came almost to the knees, effectively covering the private parts, but as fashions changed and doublets became shorter, it became necessary for men to cover their genitals with a codpiece.

By the end of the 16th century, the codpiece had been incorporated into the hose, now usually called breeches, which were roughly knee-length and featured a fly or fall front opening.

During the French Revolution, the male citizens of France adopted a working-class costume including ankle-length trousers or pantaloons in place of the aristocratic knee-breeches. This style was introduced to England in the early 19th century, possibly by Beau Brummell, and supplanted breeches as fashionable street wear by mid-century. Breeches survived into the 1930s as the plus-fours or knickers worn for active sports and by young school-boys.

Sailors may have played a role in the dissemination of trousers as a fashion around the world. In the 17th and 18th centuries, sailors wore baggy trousers known as galligaskins. Sailors were also the first to wear jeans -- trousers made of denim. These became more popular in the late 19th century in the American West, because of their ruggedness and durability."
