I used Carla's Portrait Peasant E-pattern available from You Can Make This ... I love e-patterns because there is no need for tracing the pattern just print the size you want and cut. Carla's are some of the best I've come across. They are packed full of instructions so perfect for a beginner sewer and the sizes go from 6m up to size 8years and even has an option for dolly too (which I've been commanded to sew up for Maia and Addison).
I used the Elongated Top version with the ruffle neck and ruffled cap sleeves (there are many variations of peasant top/dress in the pattern..... more bang for your buck).
