Dotted or Sprigged

One takes delight, in these curious times, in curious details, such as this passage of rare specificity in The Golden Bowl (New York Edition). Devotees of the full Henry James cosplay experience should note that Adam Verver's necktie in the first edition was 'sprigged'.

He wore every day of the year, whatever the occasion, the same little black ‘cutaway’ coat, of the fashion of his younger time; he wore the same cool-looking trousers, chequered in black and white—the proper harmony with which, he inveterately considered, was a white-dotted blue satin necktie; and, over his concave little stomach, quaintly indifferent to climates and seasons, a white duck waistcoat.
