Now with the new wardrobe/forum option I went to look at my saved outfits and a lot are missing layers and are just generally old and that I don't own those wardrobe items anymore.

Is there a way to delete saved outfits? Or do I have to save something over them?

You have to save something over them, but since the default for a slot with no HA saved is just a naked avatar, you can just save a naked avatar over them as a placeholder. I do that usually because it helps me keep track of which saved HAs I no longer need.

Thanks, don't know why I didn't think of just saving a naked one over all the others. :)
