Indeed, I am trying to sort items and am encountering the same issue. What is more, I find it easier to upload to 'My Looks' ... but then cannot transfer them to items. My graphic items didn't show on my page before they changed everything.
This is grand ... I take it that there are no limits to items in a set!!
Have you figured out how to create categories for your items? I thought I had by putting them in albums during the upload process & naming each album with a separate name. But when I go to retrieve items from a particular album, every item shows up from all the albums.
