The Irish flat cap has become a symbol of heritage and tradition, but its journey through time is far more fascinating than many realise. From early beginnings in the 1500s to its status today as a stylish accessory worn around the world, the Irish flat cap tells a story rich in history and culture.
The first known reference to the flat cap dates back to 1571. During the reign of Queen Elizabeth I, an Act of Parliament in England required all men over the age of six (except nobles and persons of high rank) to wear woollen caps on Sundays and holidays. This law aimed to boost the wool trade and quickly spread into Ireland, where the cap was embraced by working men. Although the law was repealed in 1597, the cap remained popular, particularly among the Irish, due to its practicality and affordability.
Some argue that the 1571 law was so widely followed that it laid the groundwork for the flat cap to become a staple in Irish and British wardrobes for centuries.
By the 1600s and 1700s, the Irish flat cap had firmly established itself as the headwear of the working classes. Farmers, fishermen, and tradesmen wore it daily. The flat cap was usually made from tweed or wool, materials that were warm, durable, and well suited to Ireland’s cool and often damp climate.
Key points:
During the 1800s, the Irish flat cap moved from being simply practical clothing to becoming part of the cultural image of Ireland. Large-scale emigration during the Great Famine of the 1840s meant many Irish men took their flat caps with them to countries such as the United States, Canada, and Australia. The cap soon became associated with Irish immigrants abroad.
In fact, by the late 19th century, photographs often showed Irish men in cities like New York wearing flat caps, linking the style directly to Irish communities overseas.

The early 1900s saw the Irish flat cap become fashionable beyond the working classes. Both in Ireland and abroad, men from a wide range of backgrounds adopted the cap. Its design evolved slightly, with wider peaks and variations in tweed and fabric styles.
Highlights of this period:
While younger generations in the mid-20th century often favoured more modern headwear, the Irish flat cap continued to hold strong cultural value. In the 1950s and 1960s, the cap was often associated with older Irish men, but in the 1970s, it began to make a comeback among younger people as part of a retro trend.
Key points:
During the 1980s and 1990s, the Irish flat cap saw a resurgence, partly thanks to Irish cultural exports such as music, films, and television. The global Irish diaspora embraced the cap as a way of showing heritage and pride.
The rise of Irish-themed pubs around the world in the 1990s often featured bar staff wearing Irish flat caps as part of their uniform.
From the early 2000s onwards, the Irish flat cap became a fashion statement as well as a symbol of tradition. Celebrities and public figures began wearing flat caps, bringing them back into mainstream style. Designers updated the classic look with new fabrics, colours, and styles.
