If you decide to sew it, I would suggest a few things... don't use the costume fabric. That's what I used and I swear, that fabric will fall apart if you look at it the wrong way. If I had it to do over, I'd buy cotton or maybe look for something else that doesn't fray too much. Also, I didn't follow the pattern exactly. There were some things I couldn't quite figure out, so I just did the best I could. It turned out okay, so I guess those things weren't all that important! haha! I also made the bow from the pattern, but then just attached it to a fabric covered headband because I knew my 2 year old would not keep the band from the pattern in her hair for long. The headband worked out great. I just hot glued the bow to the fabric covered headband (also hot glued).
The dress also has a cape and a white collar. My daughter would not wear the collar (it's stiff and stands up around the face), but she does like the cape!
