I think Addison just might be a future trendsetter.
Notice the highlights of this outfit: She has on one regular brown sandal and one Dora slipper (we have a major love of shoes in this house!). That's a bright blue bow holding up the 'Pebbles' hairdo. Of course the bow in no way matches anything else she has on. And that would be a miniature slinky she's holding in her mouth.
Obviously, she has to keep her hands free to switch out shoes every five minutes.
