Royston John Trevail returns from serving in the First World War in the Duke of Cornwall's Light Infantry, and stakes his future on the opening of a Gentlemens Outfitters on River Street in the city of Truro. He runs a country round on a converted motorcycle, delivering clothes throughout Cornwall.

Royston's son Geoffrey serves throughout the Second World War, in the DCLI like his father. On his return in 1946 he finds that "and son" had been added to the shop facia. At this time Mr Trevail senior dies suddenly and it is largely left to Geoffrey to build on the reputation for friendly service. He takes over in 1953 when Royston dies.

Geoffrey Trevail buys 31 River Street to open a boys and schoolwear shop. With his wife Joan, he embarks on an ambitious modernisation and expansion of the business. In the late 60s he is joined by his only son Nicholas.

Throughout the 60s and 70s Geoffrey and son Nicholas run the store while Joan expands the womenswear offering. In the late 90s Trevails gets an embroidery department. Soon Nicholas is fitting male voice choirs, rugby teams and yacht crews with embroidered blazers, shirts, and Tshirts.

Royston's great grandson Olly takes over as buyer and manager for Trevails in 2009, while Nicholas continues to run the business.

The emphasis on quality, style, and personal service is the same as it always was, and Olly, Nick and their fantastic team are celebrating the centenary of this very special family business.
