This is a child’s pillowcase dress from a purple patterned cotton for a three year old who plays outside a lot. About 22 inches from neckline to hem, with a drawstring and a front pocket.
I used purple thread for all the stitiching except the shoulder straps, and wish I'd switched to white for everything except the decorative flowers. It just looks a little 'handmade' to me with the purple. Also, I made the pocket out of a double-thick scrap of fabric, and should have just made it single layer and two pockets.
