Put on the silver mesh chainmail sleeves and hood first as your base layer.
- 2
Pull the white sun-crested tunic over the chainmail, ensuring the silver sleeves show underneath.

- 6
Slide the toy sword into your belt loop or scabbard.

Makeup & hair
Keep facial hair natural or wear a fake brown mustache and short beard. No heavy makeup is required; a clean, slightly weathered face fits the medieval traveler aesthetic.

King Arthur costume FAQ
- How do I get the sun logo on the tunic?
- You can buy a pre-made tunic online, or paint the smiling yellow sun onto a plain white tunic using yellow and black fabric paint.
- What is the best way to mimic chainmail?
- Open-weave silver mesh fabric or metallic-flecked grey knitted fabric works best to mimic chainmail without the heavy weight of real metal.
- Do I need a horse for this costume?
- No horse needed! In true Monty Python fashion, you just need a friend behind you banging two coconut halves together to mimic hoofbeats.
Did you know? Because the film's budget was too low to afford actual horses, the filmmakers decided to have the actors pretend to ride horses while squires banged coconut halves together, creating one of the most famous running jokes in cinema history.
