Save to Shared Outfits not working since my wardrobe was broken last week. I was so excited to have my missing wardrobe back I didn't want to complain...anyway when I click on it no confirmation and outfit isn't saved.
Did your outfit involve a skin by any chance? Yesterday when I was trying to save an outfit, it didn't save or display a confirmation until I removed the skin I had on before entering the wardrobe. Re-equipping it still allowed me to save (until I refreshed the page) so I don't think it's an issue with that particular skin either.
