I may be posting in this thread merely to get the response I am looking for, but I need some advice. I am in the process of planning out my wedding attire, and I've figured out that from the waist down I'll be in dark denim and boots (likely Wolverine 1000s or some Red Wing Heritage). From the waist up, I am interested in doing a vest/blazer combination in (brown, or warm) tweed. I'm not set on both being tweed, as I've seen some combinations of tweed/solid that have looked pretty good.
When I asked this question on Reddit's MFA (I'm new here so I don't know what, if any, politics exist), I got the knee-jerk reaction of not pairing waistcoats with jeans. I understand that rule of thumb - shiny suit vests and jeans is bad news bears.
My pinterest page (pinterest.com/irishexpatriate/clothing-for-the-day/) includes quite a few examples of tweed blazers and waistcoats. Am I barking up a dangerous tree here? Was MFA correct? Do I need to follow any rules? Should I pair a cardigan with a tweed blazer? Help me out.
