To my surprise when I was making a new outfit in the Beta wardrobe I was trying on a lot of items. I ended up forgetting an item because it was unchecked in my list and and when I saved the outfit, the hidden (unchecked) Custom Wearable which I do not own was saved as part of the HA.
I don't think its right that people would be able to do this and save HAs with wearables they don't own. Please fix this bug.
Preview screenshots with HA wearing item I do not own:
In the Beta Wardobe when I load the previously saved outfit.

When I select that outfit in a post after selecting "Choose outfit"

Please see spoiler with a test I did before submitting this post. This is extremely broken and can be abused. This NEEDS to be fixed.
TEST WITH A FULL SET OF ITEMS I DO NOT OWN = SUCCESSFUL!
So I decided to go ahead and try to see what would happen if there was limit to how many items I don't own could be saved, apparently there is no limit. I made an outfit completely out of items I do not own here are screenshots.
View of Beta Wardrobe as proof I own NOTHING.

Was able to save the outfit as is.

Was even able to use it in a forum post with "choose outfit".
I use Google Chrome on a Windows 7 64bit machine if that helps in any way. Thank you for your time.
Cyroris asked me to test this to see if it was just her. I was able to replicate it.
My current outfit is also comprised of items I do not own as proof.
Please fix this!
Are you able to just wear it outright, or only when you click choose outfit?
Because it seems like an oversight that the Choose Outfit feature lets you wear outfits with items you don't own. You've always been able to save them without it.
I get an error message if I try and save it outright to my HA (which is a good thing really)
Image of what I got when I tried to save it to my current HA and not an outfit:

Still don't think outfits should be allowed to save items you don't own. D:
I don't have a problem with them saving outfits you don't own, but there should also be an error if you try to select them, or the Choose Outfit button should pull from a different set of avatars than your regular save section or something :L
Yeah I think it would be fine if you could save the outfit so long as you aren't able to use it on the forums and stuff. I like what you said though if you don't own all the items on a saved outfit that it shouldn't show up under the "choose outfit" option. That would probably make this no longer an issue. I just foresee people abusing it and showing off wearing privates and things they don't own.
Has anyone noticed this still happening?
The choose outfit thing was disabled awhile back, so no :x
