I used the Chloe Dress from Imagine Gnats for the doll, but made some modifications to make it fit this Our Generation Doll from Target. I think the sizing between 18″ dolls is mostly the same, but there are some differences in the shoulders (these doll are made like a linebacker!) and chest/torso circumference. I added 1/4″ to the back seam allowance to make it fit this doll better. I used the faux cap sleeve option on this which makes it a super quick sew!
