A red and white bikini (Misty's Original Game Outfit)

After a bit of searching, Ash grabbed a hanger and pulled it out.

"Huh..." she thought, examining this garment. Sure, it hadn't been the trainer's intention to pull out a bikini of all things. Sure, Misty's regular outfit was by no means the sort of thing that a ten-year old should be wearing. But something like this seemed... scandalous, for lack of a better word. "Hm... this would be a nice change from her usual stuff."

Stripping out of her current clothes, Ash got to work getting the bikini on. Sure, she looked to have not worn it in some time. But that didn't stop the garment from still fitting.

"Perfect."

Blowing a kiss to the mirror, the 'gym leader' headed out. If she was lucky, this should be enough time to get the gym ready for the first challenger. Or perhaps some kind of hint would be revealed to explain the strange situation she had found herself in for the moment.

If not, Ash could just make the most of this change. Maybe even forge her own path.
