I will likely be going to Europe next year. Spain is a strong possibility, but it might be France and/or Italy.

My question has to do with visiting churches. From the various guide books I've been reading, many Catholic churches prohibit entry to people wearing shorts and other such "immodest" clothing. Am I likely to encounter any problems if I wanted to see the inside of a church while wearing a kilt? Any suggestions on how to handle a frantic docent who is trying to shoo me out because of my "skirt"?
