@Doozer - When you go to "add/edit items" and click on one of the items you've uploaded, there's a drop-down bar for category. I don't know if this overwrites the old item or makes a new one in the new category. Hope this helps!
This is gorgeous sweetie!! I know I accidentally listed my vintage tropical dress under jeans. I haven't figured out how to correct things or delete things. Have a wonderful day!! XXO
