For some reason, the wardrobe isn't letting me wear anything but the outfit I'm already wearing, and the wear and save outfit buttons do nothing. Anyone else is having the same problem? D:

Changing outfits takes a short while for it to show up. If it hasn't shown up after ~15 minutes, try making another outfit, saving that, and trying to wear that. If it still doesn't show up, I suggest clearing your cache, trying another browser, etc.

If all else fails, file a ticket and hope someone can figure out what's going on.

Make sure you don't have too many items on one layer.

If you are using Salon hair, you may need to go reset it (in the Salon section of your wardrobe). That sometimes causes problems with HA saves and updates. You can re-do your hair afterwards.

I've discovered. There were too many itens on the head layer, silly me. How do I get this forum tread locked now? I'm a bit of a forum newbie :(

You can ping one of this forum's minimods or submit a ticket via the Ticket Center. :)
