First - from Boston, Massachusetts.
Second: Measure very carefully, and I recommend a SWK Standard over the thrifty kilt, well worth the little bit extra that it costs. See my avatar for my SWK Standard in Irish National Tartan with necktie and flashes. With kilt belt sporran and well shined shoes, I get noticed in a positive way. Be ready to display it proudly. The wearer of a kilt is displaying a self confidence that is not found by wearing the generic style of ones peers, but is making a statement of pride and confidence in himself to be unique. This is noticed by the opposite sex. If you are just experimenting to see if the kilted lifestyle is for you, I recommend the standard over the thrifty. I own a thrifty in Black Watch Tartan. I use this as my around the house and in the neighbourhood kilt. I also have two solid colour kilts. One I made from Black denim, and a forest green from Amerikilt. I do not know if your school has a dress code that prohibits the kilt, but I highly doubt it, especially if you have any form of Celtic heritage. Be prepared to have a little bit of historical information in mind for the questions you will be asked.
