The back of the dress is drawn up with elastic to make it adapt to the small little backs that it must fit around. (I am watching a rendition of Mansfield Park right now, so I am perhaps sounding a little 19th century British as I write.)
I waited to enter these pictures for want of receiving a picture with the little Ellery wearing it, but I thought I'd now go ahead anyway. Maybe later.
(Update: When we went to SoCal for Thanksgiving, Cossette wore this cute little dress. Below are a couple pictures from that day.)
Now the cute little 3 year old is telling quite a story, and we can see the front of the dress pretty well.
