I do seem to remember a number of my friends bemoaning the lack of affordable, well-made, cotton clerical shirts. These are fair trade, but I don’t think that should put you off if they fit the bill in other respects. They are also asking for suggestions of colours to expand their range.
ETA: On closer inspection, I am amused to see that one of the Butlers who make up ‘Butler and Butler’ is none other than Simon Butler, who many years ago lived in the room next to mine at Oak Hill. As I recall, he funded his way through college by running a car-import business. Clearly the entrepreneurial spirit lives on.
