We can assume the costume we know is for gym battles or public appearances, since we know Lance's family and dragon tamers as a whole have a flair for theatrics and traditions.
As for the original question, her gen 2 design is peak. In a lineup of 7 other gym leaders that dress and act like normal civilians relative to their towns, Clair stands out as still somewhat normal, but with the cape for flair. Like how Lance stands out as showboaty in his dress and speech compared to the others, save for Will, who is just some homo vagrant they let sneak in to guard Koga.
