This is an unused IKEA pillowcase that I picked up from Vinnies for $2 + some scraps from this dress + ric-rac. I cut the closed end of the pillowcase open, cut some dips for the underarms, added the yoke pieces, finished the arm holes with bias tape and trimmed the bottom with ric-rac. The long sides of the pillowcase became the side seams of the dress. Because the body is just a slightly-gathered rectangle it is pretty boxy, but hopefully in a "60s-shift-dress" way, not a "Hello-here-I-am-wearing-a-pillowcase" way. Because that would be a bit weird.
