The right fit is essential for both comfort and style. A well-fitting flat cap should feel secure without being tight, sit correctly on your head, and complement your face shape.
A flat cap is a rounded, soft-crowned hat with a short, stiff brim at the front. First appearing in Northern England in the 14th century, flat caps became embedded in British and Irish life after a 1571 law encouraged their wear among men of the working classes. By the late 19th and early 20th century, they were worn by everyone from labourers and farmers to gentlemen at leisure. Today, the flat cap retains its heritage charm while being embraced as a versatile style in both town and country.
A flat cap is one of the most versatile hats you can own. Whether you are dressing for a weekend walk, a day in the city, or a smart country wedding, the flat cap adds effortless polish while remaining comfortable and practical. Here is everything you need to know about wearing one with confidence.
Flat caps are designed to last for years, but proper care is key to maintaining their shape, colour, and quality. Different materials -wool, tweed, linen, leather - require slightly different cleaning approaches.
Flat caps are travel-friendly by design, but a little care goes a long way in keeping them looking sharp - whether you are storing them at home or packing them for a trip.
Getting the right size is the key to a perfect fit. Here’s how to measure your head accurately and choose the right flat cap size.
