Despite the complex looking metal armour and chainmail, a medieval knight costume is much easier to make than you might think. Creating your own costume is often much cheaper than buying or hiring one from a fancy dress shop. Assembling simple pieces such as a white T-shirt, trousers and a few accessories can produce a realistic knight costume.
Buy an oversized white shirt that is one to two sizes larger than your usual size. Wash the shirt before beginning work on your costume.
Create a cross on the white shirt. Take a large piece of red felt material and trace a cross on the material with a pen. After you have traced the desired shape, use scissors to cut out the cross.
Glue the cross to the shirt. Lay the shirt flat on a table and choose where you would like the cross to be. Use a glue gun to stick the cross to the shirt.
Choose a pair of black trousers to finish the costume. Select a pair of snug-fitting black tracksuit bottoms.
Create a sash. Buy around 1.8 metres (2 yards) of brown fabric to create a sash for your waist. Measure your waist, and make a sash that is twice as long as the measurement. For example, if your waist is 75 cm (30 inches), cut a sash that is 150 cm (60 inches) long and about 12.5 cm (5 inches) wide.
Choose a few simple accessories to for your knight costume. You can find a knight helmet, faux chain mail tabard and sword at your local toy or arts and crafts shop.
When sticking the felt to the white shirt, make sure to handle the material with care. Glue guns can get very hot.
