Iris's outfit

Staring in, Ash was met with Iris's outfit.

"Huh." the trainer thought and stripped out of his clothes. Throwing them off to the side, Ash had a feeling that Iris was likely to dispose of them once they got to their final destination. At least, he hoped that she would.

Starting off with the undergarments, Ash took care to slip them on. Then came the matter of smoothing it all out to maintain the illusion that he was a girl and not a boy. While that did take a bit of time, the results were very much worth it.

Then came the leggings. While Ash didn't consider himself the sort to wear that kind of clothing, they looked sturdy and would hold up well to whatever was thrown at her.

Next came the top. Coming with some slight padding, it would improve the illusion immensely. Bringing it down, Ash smoothed it out.

That just left the slip-on shoes.

"Now, what to call myself?" she thought, taking a moment to think it over. Only one name came to mind here. "Ivy."

Yes, that would be perfect.
