Good topic, and as a Christian, one that is close to my heart.

I wear kilts full time so when it comes to church - that's what I wear.
Apart from preaching in our own fellowship I often visit other churches.
I've been to Presbyterian, Anglican, Catholic, Penticostal, Seventh Day Adventist, Baptist and more.
I've never had a problem or a negative comment from any church member, on the contrary, only compliments.

I take the point about being "center of attention", I've heard it before but respectfully disagree.
Sure, the kilt is a talking point when walking into church, having a fellowship cuppa or walking out, but in worship I see that all folk are focussed on what they are there for.
I've found that the kilt has really broken the ice and opened up interesting conversations (not that there is much ice in church haha!).

Church is the best time of the week, why not wear the best male garment there is?
