The bonnet is one of the oldest and most semantically overloaded words in hat history. It has referred to men's everyday outdoor hats in 15th-century Scotland, to the elaborate decorative women's hats of the 18th and 19th centuries, to simple children's head coverings in the 20th century, and to car hoods in British English -- all through the same word in continuous use. Understanding each of these is understanding how a basic concept (a cloth or felt covering for the head) expressed itself differently across centuries, genders, and geographies.
The Word and Its Earliest Use
The word bonnet (from Old French bonet, a type of fabric) entered English in the 15th century to describe cloth hats of various kinds. In its earliest English use, it was not specifically a women's hat -- men's soft cloth hats and caps were frequently called bonnets in English and Scottish documents of the 15th and 16th centuries. The Scottish blue bonnet (a flat, round, blue wool cap, distinct from the brimmed hat tradition of England) was specifically a men's everyday working and fighting hat and one of the earliest forms to which the word referred in regular use.
The word maintained different meanings in Scotland (where it continued to refer to men's caps longer) and in England (where it began to move toward women's headwear associations earlier). The Scottish Highland bonnet and Balmoral bonnet -- structured round or bearskin-based military caps -- retain the original male association in their names to the present.
The Georgian and Victorian Bonnet
The bonnet's most culturally significant period was the Georgian and Victorian era (approximately 1750-1890), during which it became the dominant outdoor headwear for women in Britain and its cultural sphere. The Georgian bonnet evolved from simple mob caps (indoor) and riding hats to elaborate outdoor constructions with significantly projecting brims, ribbons, flowers, feathers, and other decoration tied under the chin.
The projecting forward brim of the Victorian bonnet was not merely decorative -- it served as a privacy shield. The brim blocked lateral sight lines, meaning a woman in a bonnet could only see what was directly in front of her and could not easily look sideways without turning. This created a physical modesty screen and was understood contemporaneously as an expression of feminine propriety. Period reformers and feminists sometimes criticised the bonnet for this reason -- it literally restricted women's field of vision.
Bonnet size and brim projection went through significant fashion cycles. The late Georgian and Regency period produced large bonnets with very wide brims; the early Victorian period produced the poke bonnet with an extremely exaggerated forward projection; later Victorian fashion produced progressively smaller, more backward-sitting bonnets that eventually ceased to frame the face at all and perched on the back of the head.
The Baby and Children's Bonnet
The small, soft, close-fitting bonnet tied under the chin for infants and young children -- which is what most contemporary users first think of when they hear the word -- is a survival of the older bonnet form adapted for specific child-protective purposes. The ties under the chin kept the hat on a child who could not manage their own clothing; the soft construction was comfortable against infants' heads.
Infant bonnets for warmth and sun protection remain in use today, though significantly simplified from the elaborate lace and ribbon confections of Victorian and Edwardian children's wear. The contemporary infant bonnet is typically a simple cotton or organic fabric construction focused on sun protection (wide brim) or cold protection (wool or fleece with ear coverage).
The Scottish Balmoral Bonnet
The Balmoral bonnet -- a flat, round, somewhat rigid cap in dark blue with a diced band and a red pompom -- is the Highland Scottish formal and military bonnet associated with Scottish regiments in the British Army and with Highland dress generally. It is named for Balmoral Castle and became widely promoted through Queen Victoria's enthusiastic adoption of Highland culture and dress in the mid-19th century. The Balmoral is men's headwear associated with formal Highland dress occasions.
The Easter Bonnet Tradition
The Easter bonnet -- a new or elaborately decorated spring hat worn on Easter Sunday -- is a tradition with roots in the Christian practice of wearing new clothes at Easter as a symbol of spiritual renewal, combined with the practical spring hat-buying that coincided with the arrival of the new season. The tradition was particularly strong in 19th-century America and Britain, producing an annual commercial context for hat buying that also produced the Bonnet Parade tradition (most famously associated with New York City's Easter Parade on Fifth Avenue).
The Easter bonnet today is more cultural reference than active practice in most contexts -- the specific tradition of purchasing and wearing a new spring hat on Easter Sunday is maintained in some communities and fashion events but is no longer a mainstream annual custom.

Frequently Asked Questions
When did the bonnet stop being everyday women's wear?
The transition away from the bonnet as everyday women's outdoor wear happened through the 1870s-1900s, as the bonnet was progressively displaced by smaller hat styles that sat on the head rather than framing the face. The bonnet's projecting brim became unfashionable as the ideal position for women's headwear moved from the face-framing front to the top-of-head placement that characterised the Edwardian large hat of the 1900s-1910s. By 1910, the bonnet was already associated with elderly women and old-fashioned dress in most Western contexts.
Is a mob cap a bonnet?
The mob cap (a large, round, indoor cloth cap tied under the chin) is sometimes classified as a bonnet variant and sometimes as a distinct category. In historical usage, the terms sometimes overlap. The distinction is primarily between indoor and outdoor wear -- the mob cap was typically an indoor domestic head covering, while the bonnet (in its Georgian-Victorian sense) was the outdoor hat that served as protection and modesty cover when leaving the house. Both are tied under the chin; the bonnet has a more structured, often wired brim; the mob cap is generally softer and rounder.
Why did Victorian bonnets tie under the chin?
The chin ribbon or tie served the same function as a modern chin cord on an outdoor hat: securing the hat against wind and movement without the need to hold it in place. The bonnet's projecting brim acted as a sail in wind, and without the chin tie it would have been impractical outdoors. The tie became a fashion convention in its own right -- the width, colour, and bow style of the bonnet ribbon were subjects of fashion attention -- but its origin was entirely practical.
What is a poke bonnet?
A poke bonnet is a bonnet style with an extremely exaggerated forward-projecting brim -- the brim extends far in front of the face (sometimes 15-20 cm beyond the face level), creating a tunnel-like projection. The style was at its most extreme in the 1820s-1830s and is one of the most distinctive silhouettes in 19th-century fashion history. The poke effect was created by wiring the brim to maintain its forward projection; the resulting shape allowed the wearer to see only what was directly ahead, with virtually no lateral vision. Period caricaturists made much of the style's impracticality.
