All I had to do was make a basic tube dress out of a 6x6 inch square of blue jersey matterial. [Hand Stitched]
After making this tube dress, I then wrapped a pretty dotted ribbon around the waist as an Obi. (For thos who don't know what an Obi is, its basically the style of sash usually found on a Kimono).
The barbie looks good with or without the sash, but I prefer to leave it on.
