Pillow Case Dress

Ok, I love to sew, can, cook, bake, garden, snuggle, hike, swim, camp...etc.. But right now because it is cold outside I am in sewing mode. I saw the CUTEST pillow case dress. Does anyone have a pattern for these? I would love to make one for the Princess. Also how about A-line elastic waistband skirts?  Let me know please :)
