Berwich

Berwich makes trousers and little else. Its own website describes the brand as a company that imagines, creates, researches and invests in making what it calls the true made in Italy trouser, and it wants to translate the trouser into many languages and many "worlds".

The detail to look for is the button. Berwich uses a discreet five-hole button, rather than the usual two or four. The five holes echo the points of the W in the brand's name, and the thread is sewn through them to form a raised W, which the brand says underlines the tailored character of each pair.

In the UK, The Local Merchants stocks Berwich trousers, describing them as classical menswear with a sartorial style.
