Two Centuries of Costume in America…
“ The term “coif,” spelt in various ways, quoif, quoiffe, coiffer, ciffer, quoiffer, has been held to apply to the French hood; but it certainly did not in America, for I find often in inventories side by side items of black silk hoods and another of quoifs, which I believe were the white undercaps worn with the French hood; just as a coif was the close undercap for men’s wear. ”
