A beefeater hat is usually worn by both men and women but is usually worn by the Yeomen Warders of England. The hats which they wear are very easy to sew and are usually sewn by hand. If the damage is too much, you can sew the hat with the help of a machine. Making a new hat is also quite easy to do. All you need is fabric and a soft plastic to insert in it. You can look at the shape of it and sew it accordingly. Yeomen Warders are considered to be the guards of the tower of London under the rule of Her Majesty. They are more famously known as Beefeaters and their hat is known as a Beefeater's hat. The Yeomen Warders have been guarding the Tower of London since 1485.
