Architecture and Upper-class ladies’ clothes liked to include nautical motifs in the Edwardian era as a tribute to the popularity of oceanside resorts, yachting, and ocean travel. Even the Crown Princess Cecilia in Potsdam designed the Cecilienhof to resemble the interior of a ship with portholes that overlooked a lake. Aboard the Lusitania Dora wore a dress with a nautical collar like the one in the picture on www.edwardwarethrillers.org.
