Recently while researching for my next novel, I did a little searching about the use of handkerchiefs. Apparently, they had a language of their own just like fans. This is definitely another interesting tidbit to add to your reality shelves while reading historical romance. Have you found any books referencing the handkerchief flirt? Enjoy.
Flirting or coquetry remained an art form throughout the Georgian, Regency, and Victorian Eras, and handkerchiefs and flirting language became all the rage.
