Evander Berry Wall (January 14, 1861 – May 4, 1940[2]) was a New York City socialite and later an American expatriate in France during the Belle Époque and beyond.

He generally wore a "very extraordinary costume"[1] such as the one pictured on the right: "a dust coat of a reddish havana brown, a suit made of a large grey shepherd plaid check; extremely wide trousers tapered at the ankle, and turned up several inches to display white spats and highly varnished shoes; a 'startling' striped shirt in red and sky blue, with very high false collar of a pattern different from the shirts, a striped vest and a widely spread stock-cravat.

[10] He appeared on the race track "in one flashy ensemble after the other until, exhausted but victorious he at last entered the ballroom of the United States Hotel in faultless evening attire.

The white ensemble had been sent to him by the London Savile Row tailor Henry Poole & Co "to be worn for a quiet dinner at home or at an evening's entertainment at a summer resort."

[5] Whether in Paris, Deauville, Biarritz, or Aix-les-Bains, Wall and his wife were famous members of the European social elite.

Their social circle included the Duchess of Windsor, the Grand Duke Dimitri of Russia, the Aga Khan, and ex-king Nicholas of Montenegro (whom Wall called a "magnificent old darling").

[7] This was located conveniently near the bespoke shirtmaker Charvet, where Wall had his signature "spread eagle" collar shirts and cravats custom-made for himself and his dog.

[7] In Neither Pest Nor Puritan, Wall ascribed his longevity to the fact he never saw physicians and always drank champagne[13] instead of water, claiming that "There are more old drunkards than there are old doctors.
