From a few feet away, it looks run of the mill. For a brown three piece suit anyway. Perhaps a larger check than is commonly seen.
Upon closer examination, the cloth is definitely an unusually large check. And the single breasted jacket is worn over a shawl lapelled double breasted vest. That is country cloth with city detailing, a favorite of the Apparel Arts crowd in the 1930s.
Worn with dark oak Edward Green brogues, a DJA royal oxford shirt from MyTailor.com, and a printed silk square and navy with white dot bow tie by Cravate Royale.
