Oh weird, it looks like only the Custom Wearables tab works when you're on the base pane in the beta wardrobe. I'll let the programmers know.

It turns out that the beta is going to be phased out really soon so from now on, it will be better to use the v3 wardrobe here. And make sure you don't have adblock on that page or it won't show anything but a blank page.

I would try just turning it off for a moment on that page (not just whitelist) to see if you can get it to work because I am pretty sure in the next week or so, the other two wardrobes won't be available at all. I think Chrome and Opera is dropping the support of the coding used in the older two.

Should not be an issue since the new wardrobe has been released.
