Decent selection of shirts - flannel / oxford / gingham check. Much better priced than the likes of Gitman etc. made in London using period machinery (I have no idea whether that's supposed to be better or not).

Surely that's just more of a traditional/ classic fit as opposed to the recent fad for slimming everything down?

Just under 23" on a size L is hardly tent territory, particularly if you look at brands like EG, Post Overalls, Tenderloin etc. and I know they are more formal shirts but it doesn't seem massively oversized to me.
