I am a great fan of the National Portrait Gallery in London...
But also in online sites like BBC - Your Paintings much sartorial insight is available.
At the BBC website you can create an account and build a collection of your own.
I discovered the British painter William Carter (1863-1939) who has made some very fine portraits of men of stature. Mr. Carter was born in Swaffham, Norfolk and his brother was the famous Egyptologist Howard Carter. Link to my collection of William Carter paintings.
In the portraits you can find much inspiration; let me give you a few examples.
First this Gentleman (Lieutenant-Colonel John Sancroft Holmes) in country attire; I find this portrait a great inspiration for walks in the countryside - the detachable round collar; the waistcoat with lapels;the Derby (bowler hat) and the shooting stick. This year I plan to buy a Derby - presumably from Christy's Hats (their fur felt Derby) - mainly for use in the countryside, but also occasionally in town.
