 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").They lived in a suite in the Hotel Meurice, with a consecutive string of chow dogs named Chi-Chi or Toi-Toi.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.
