In the wardrobe, I tried to put on the Off-White Undead Lace Edge Shirt on my female HA, but the overlay changed to the male version. It's only for that particular item that I've noticed.

Were you using the beta wardrobe? Sometimes in the beta wardrobe, items will show up as the opposite sex overlay.

- I was in the beta wardrobe. It showed the correct preview when I hovered over the item, but when I actually selected it to put it on, it was wrong. Is this a common thing?

It happens from time to time, but isn't permanent. Usually you just gotta give it a really good refresh. Idk what causes it, but I've encountered it several times.

This happens to me too but refreshing doesn't seem to fix it. All my clothes show up as male versions. Seems fine once you save and use the outfit.
