We used to have shirts, when I was a child, in which the collars were stiffened by plastic tabs.  You could remove them.  Now there are shirts where you can't remove the tabs.  Look at the average shirt collar on the average Englishman, particularly when he's wearing one of his hideous lurid ties.  Makes you want to weep, doesn't it?  Is there a more appalling creation than the 'English' (Third World) 'button-down'?  Others might as well be constructed of cardboard.  B.D. Baggie doesn't have much of a reputation - and, it's true, their collars don't have much of a roll - but their collars soften nicely, particularly on the u.s. and look nicely Ivy-soft if worn unbuttoned. 

Kingstonian is right, however.  Life is generally too short for going into charity shops.  Handling the average shirt can bring on apoplexy. 

And some of the worst examples would have been the most expensive.

There is nothing, aside from shoes, more important than the shirt.  Which is why they get talked about so much on the forum.

My vote still goes to American made Brooks.
