KC,
Not all the time, but I will wear the kilt to church a few times a year. Like you, church was the first place I wore a kilt. While wearing a kilt is definitely a sign of a refined sensibility, I am not sure I would equate it to being close to God. On the other hand, I also do not find it to be an impediment to becoming close to God. Also, if your Pastor will go to a pub with you while you are kilted, he may yet consider a "kilt day" at the church.

Grace and peace,
