Her pattern was very easy to follow. You do have to be at least an advanced beginner to follow along but she gives excellent explanations of everything. I did cut out my fabric a little differently than the pattern said just so I would have enough fabric for my dress. I bought what the pattern suggested for her size but when I cut out the first dress for my other daughter, I did not have enough fabric in the end.
My older twin daughter just wore this one for the first time recently and she loved it. She is such a little string bean though that the sash kept moving south on her but she got used to it. I would definitely suggest trying her patterns and dressing up your little girl in fun, bright colors!
