Back in December 2005, Monty Don, the British horticulturalist and human Peter Rabbit, wrote a delightful little essay for The Guardian on how to dress as a gardener. The piece was filled with Don’s personal rules and prejudices, which, when delivered with a bit of humour, tend to produce the best kind of menswear writing. Jeans and tight trousers, he warned, are uncomfortable and restrictive. Pockets should be just large enough to hold a penknife, string, a pencil and perhaps a mint or two, but not so cavernous that retrieving things becomes an excavation. In winter, the BBC presenter favours thornproof tweed jackets layered over a waistcoat or thick turtleneck, even if others feel this looks a bit patrician.
