Have tried to wear and save but also share HA but it doesn't take. Can someone please instruct me? Thank you.

you need go to the outfit page in the wardrobe and copy the scode below the wear/delete buttons Outfit Not Found Outfit Not Found

That sounds like I should post it somewhere? I have the code but where do I put it?

i was assuming you were going to post it somewhere on the forums o: if you just wanted a url to send to someone, i think if you click on the outfit image in the wardrobe, it should give you a public/shareable url, like this one? otherwise you would want this url, but i'm not sure what's the easiest way to get to that without using subeta.net/shared.php?userid=72374 (like, i don't know where that page is in the new wardrobe)

Before I try the wrong possibility - which one would I use to post my shared HA in a post showing my HA as outfit created by?

EDIT: Oops, figured it out. Thank you so much for your help!
