The hat is another great Annie's Attic pattern. I really wish these were still available. They fit the Pocket Spirits perfectly.
The dress is an adaptation of the camisole pattern, an easy side to side bodice that is very forgiving. This Pocket Spirit has a jointed shoulder, similar to the way the head is jointed, using a 9mm acrylic eye as the joint. Gives her a little more pose-ability, but the armholes in the clothing need to be a little larger to accommodate the joint.
