James is a young boy with fair skin, blond hair and hazel eyes. His prominent outfit is a white vest with a green jacket, a golden badge in the shape of a star, a teal bowtie, brown pants, white stockings, and black laceless shoes. Other outfits of his tend to be the same, the only difference generally being the color scheme. So far, his jackets have been light green, dark green (worn on Wassalia), light blue (worn for his father's wedding to Miranda), dark blue (worn for the School Fair) and dark red (worn for Sofia's debut ball).
For Flying Derby, James wears the school riding uniform; a pink shirt under an aqua waistcoat with the school crest, khaki trousers, and black calf-length boots. He also wears a light blue helmet.
When he and his family became bakers in "The Baker King", James wore clothing more in line with a village boy, namely a beige shirt under a brown waistcoat, a green necktie, yellow trousers, white stockings, and black shoes. He wore a nearly identical outfit in "Tri-Kingdom Picnic", the only difference being the necktie color.
