Elenita is dressed as her little piggy, affectionately known as "chancho". I made it a year ago and pretty quickly had to make a second one so she had one at school too. It's quite loved (and chewed on).
The pattern for the sweatshirt is the Bimaa sweater which I hadn't seen until last week's KCW and it was exactly what I had in mind. In fact, I was planning on making my own pattern with raglan sleeves (that's where this one is a little different), and a three piece hood--this one was perfect. The fabric is sort of a stretch terry and it's the same fabric her stuffed pig is made of.
The ears, nose and tail come from the Abby Glassenberg Lovey pattern--I just made the ears and nose a little bigger but left the tail the same size. I also decided not to stuff the tail and I think it works a little better that way.
As you can see, Elena loves her chancho costume. So much so, she kissed the snout as soon as I showed it to her the first time.
Happy Halloween everyone.
