Here you can see I pulled up some references, the teal prince was brought in earliest and actually influenced most of the outfits past that orange one in part 1

Here you can see I drew each outfit in my own way (with slight changes) and then at the bottom I tried to combine them with a little inspiration from the bottom left outfit and the top of Ariel's sleeves. I has mostly put the outfits I drew over each other and drawn over like the middle ground of the overlapping lines
