If you have not seen this done before, count your blessings. I see it done frequently and it never looks right to me. Sean Connery is one of the worst offenders.

I agree with Jock. Go with a black barathea Argyle jacket, worn with or without a 5 button waistcoat. You will also likely find more occasions to wear it after your wedding. Plus you can wear this style of jacket equally well with bow-tie and 3 button formal waistcoat.
