Many of the wedding I've attended have people wearing PC jackets during the day and I'm sure if you asked them about the PC being an evening / black tie outfit they would not know, and these are Scottish weddings attended by Scots. Most of my friends and relatives have only one kilt and jacket so this would be worn to all occasions and people like to dress up smart so the PC gets worn during the day.

I actually like the look and feel of the PC more than my Argyle but usually only wear the PC for black tie events. I've never seen anyone comment about what people wear........as long as you're having a good time then thats more important
