I'd still like to find a way that I can wear un-tucked shirts and a blazer for a casual look.
I suppose Oxford cloth shirts are not right. I know that whenever i've attempted to pair them with any of my Lanvin chinos/trousers they don't feel right at all.
Though I think the blazers I own, while some are unstructured, are still not 'slouchy' enough for what I am picturing.
