In the context of Pokémon contests, Coordinators like May often wear different dresses and costumes, which are called "Contest outfits." These outfits are usually very elaborate and are designed to match the theme of the performance in the contest. May has worn various dresses during her contests, often resembling a princess-like style with elegant and vibrant designs.
If you are looking for a specific dress or need more information on May's outfits, please provide more details or specify the event, and I can help you find more information or suggest how you can recreate the outfit for a cosplay or a viewing party!
