Zuko’s hanbok is a ‘gonryongpo(곤룡포, dragon robe), which is a robe worn by the king and the heir to the throne. The gold patterns on his chest and shoulders are called hyoongbae(흉배). The king’s has a dragon with five claws on each foot, and the crown prince’s has a dragon with four claws instead. Zuko has the king’s in this drawing.
Note: the red of the robes and the gold dragon pattern are historically accurate, but I changed the color of the clothes’ lining, belt/pumdae(품대), and shoes to fit fire nation colors better.
