I mean, first of all, it's Nishi. She likes tall women and cute short men who crossdress from time to time. Ichi is a cute short man so she already set the stage for that scenario. Second, the boots and him undressing in front of the others nonchalantly is definitely a hint towards him not giving a fuck on how he presents himself to others. The main thing he cares about is to satisfy his hunting-sexual urges. I can imagine a scenario where he crossdresses in order to bypass some witch areas without detection.
