The tartan kilt has long been the most recognizable cultural tradition of the Highland Scots. Therefore, it surprises most people that many of the most recognizable features and traditions associated with the wearing of the kilt have, in fact, been developed in the nineteenth century, not by Scottish Highlanders, but by the Nobles of England and Scotland. You can read more about the history of the kilt here.
There are basically two types of kilts, the great kilt which you would have found in the Highlands in days of long ago and the little kilt which is common today. You can find more details at the Celtic Stuff site. Be sure if you visit the site to follow the link to how to wrap a great kilt. It takes real skill.
If you want to have a kilt but do not want to pay a lot of money for it then why not try making one.
There is a whole protocol to wearing a kilt properly and if you are interested, an instructive book is available. When discussing the proper way to wear a kilt the question always comes up, "What does one wear under a kilt?" If you are curious you will find the answer here.
Once in a while you will see woman in little kilts but the appropriate Highland dress for woman is described at Tartan Web. My favourite is the Skye cape.
It was no surprise to find a kilt especially for golfing since Scotland's is the home of golf.
