Hi guys. I searched for a few threads on plaids and where the right time and place is for one. I was struck by a lot of people saying "even a Prince Charlie isnt formal enough for one"! I was actually just about to buy one - as there are a few black tie events coming up on my callendar and the most formal jacket I have is a Prince Charlie... should I scrap the idea?

I also found a lot of mention of a plaid to wear over the shoulder unbrooched with daywear. Does anyone have information and/or pictures of this?
