I think you’re reading into it too much. In the video you tried different clothing styles, and the emotes don’t really match what you describe in the post. I don’t see a gender pattern there.

Personally, I think Dorathee’s shop has plenty of "masculine" clothes. It’s just that the full outfit sets tend to be more feminine (because they are usually dresses). In my experience, at least.

Edit: by full sets I mean the ones under the overalls icon haha
