Cuteness! What about running a ribbon around each ankle, similar to a drawstring bag? Then she can decide on the tightness/looseness of each ankle, and the right pattern on the ribbon would look really cute!
I love them all, but especially the red and white and the two tone one (on the right in the photo). They both look adorable, the red one looks like I could haul all my crap around in it and it wouldn't sweat it at all (and that's quite a feat), and the two tone one looks so bright and cute! Kudos.
