This crochet outfit pattern fits my Eva doll pattern which you can find in my Ravelry store. The outfit was made using Sugar n’ Cream cotton yarn with a 3mm hook, the same size hook I used to make my doll. You should use the same yarn and hook size that you used to crochet your doll to make her clothing. My doll clothes are designed to fit snugly so they stay on but the size of your finishing clothing may vary slightly depending on how tightly or loosely you crochet. If your clothes do not fit your doll, try going up a hook size.
