Related to above I'm getting a flannel navy bold chalk stripe single button blazer suit with peak lapels.
Wish me luck.
fwiw I plan to wear it with white trousers; I think jeans would be highly incongruent and one of those fashion things that most people just look trash in them including most fashion people or celebrities.
It just looks too much like you were wearing jeans and threw on the closest jacket, whereas an outfit that harmonises more indicates intent, which makes breaking of rules more feasible IMO.
If anyone can pull off that look it's you. And I agree, blazers with denim jeans make people look like Jeremy Clarkson.
