Off shoulder sweater

Hi knitters,

I have been looking all over Ravelry and other pattern sites for a sweater similar to the one in the photo. Just want to know how to do an for shoulder sweater. Any help is appreciated! Thanks!

There are a bunch of them on Ravelry. I would think that you could take a sweater pattern and skip the neck part and cast at about the point where it would hit your shoulders. No idea how to calculate that off the cuff tough.
