If you're getting an error message like this, please make sure that
- you're wearing the HUD,
- you have RLV activated in your viewer,
- the web page is running on HTTP
Also try resetting the HUD (click the HUD's menu button on the 1o'clock position, then Setup > Reset HUD). If it doesn't help, check if wearing a brand new HUD solves the problem (you can get it redelivered in the inworld store).
If you're still running into issues, please open the browser's developer tools by hitting F12 while on the Wardrobe page, and check for any errors when you try to do something that involves the HUD (e.g., put something on).
If you see any errors, please make a screenshot and send it to me.
