I think they are actually inverted

I tried and got the male based on my female HA. xD

I made a report to staff. :)

It is only the preview that is incorrect. When you save it, it does save correctly.

Hrm! That's weird. :O

Indeed it is...it happened with the new collection dress and the rainyday ethereal top as well...may happen with other stuff. But they all save correctly.

[edit] Board about top http://subeta.net/forums.php/read/820591

Is this still a thing?

Still very much so. There are a lot of things that will save correctly but will show up in the beta wardrobe with the opposite gendered overlay.
