Mobcap

A mobcap (or mob cap or mob-cap) is a round, gathered or pleated cloth (usually linen) bonnet consisting of a caul to cover the hair, a frilled or ruffled brim, and (often) a ribbon band, worn by married women in the 18th and early 19th centuries, when it was called a "bonnet".

Originally an informal style, the bonnet became a high-fashion item as part of the adoption of simple "country" clothing in the later 18th century.

[5] The one piece, ruffled, gathered circle mobcap often seen worn with historical costumes is a simplified, modern interpretation, rather than a copy of a period cap.

Modern versions of mobcaps are still worn in the pharmaceutical industry, in clean-rooms, and in other sectors where the hair has to be contained.

These mobcaps are usually a simple circle shape with an elastic band and may be made of disposable materials such as spun-bound polypropylene so they are like a shower cap.
