Well, I had the same problem today. So I checked this out a little.
I found out that in the inventory, in the "recent" tab where the current outfit is displayed there was an item that instead of "worn" it said "invalide file.. or destroyed item or something like that..i can't recall. And I couldn't locate which one was.
So I took everything off and wear them again one by one to follow at the current outfit if it said "worn".
Then I saved the outfit and it was saved ok.
I hope I helped **Only uploaded images may be used in postings**s://secondlife.i.lithium.com/i/smilies/16x16_smiley-happy.gif" border="0" alt="Smiley Happy" title="Smiley Happy" />
