Small white caps made of linen or cotton and edged with lace were quite popular among women and young girls during the early eighteenth century. Two fashionable styles were a mobcap, which covered the head with a puffed white crown bordered by a lace edge, and a round-eared cap, which curved around the head to cover the ears and was edged with lace or ruffles. Both cap types had long fabric streamers called lappets that were left to hang down the back, tied under the chin, or pinned up on top of the cap. As hairstyles grew bigger throughout the century, caps did not. Rather than covering the whole head, caps became dainty accents pinned to the top of enormous piles of hair, often without lappets.
