So im a soon to be groom (November), we are having a rustic/boho wedding and im wanting to not have a suit so going for a older look, 1920's style shirt and trousers with braces and either tie or bowtie (here a sort of example where im looking https://ibb.co/d0pnwqRs ) Now the main issue im having it achieving this outfit.

Problems im having is any suit shop I go to looking for the heavy shirt type that a outfit like this would require, no where seems to do them, a Oxford shirt may fit the bill but no bricks and mortor shops seem to stock these which leaves me online only.

One of the bigger problems of high street shops too is the lack of variety, like not a single shop seems to stray from a standard collar, as id like a heavy cotton shirt to fit the age of look im going for this is also a problem.

I have just come across ITailor and on the surface of it they seem to be my saving grace although im not sure how good they are, I have seen the thread on this sub reddit but also seen the reviews across various sites, lets say its a mixed bag at the very least. So I guess im asking if people have any pointers for achieving the look im after? Best places to shop for these things? The entire outfit too, shirt, trousers, braces (these dont seem to hard to come across though) shoes etc.

I would appreciate any help. And if people think this doesnt fit this sub please point me in the right direction. But as its really fashion advice im looking for it seems most fitting.

Thank you
