It sounds so cute, but what a bummer about the sizing. I know the finished dress will be perfect!
Oh wow, how disappointing! I have heard about some patterns requiring that you add your own seam allowances. That does not sound like a fun extra step to deal with and if you miss that point then the outfit will end up too small. It sounds like you have a good plan in place for pulling together another dress for your daughter. Excited to see how these turn out even though it wasn't your original plan.
So I have an update on this project. I decided to make it without a skirt lining for a friend's 5 year old's birthday, and I finished it last week. It turned out really well. Then I brought it downstairs and reminded my daughter that we had agreed to give it to her friend, and she freaked out and insisted on trying it on again. She could barely get it on, but I saw how I could alter the armholes so she could wear it.
I made another one for the friend, and I am NEVER making this pattern again. It's awful. The bodice goes together in an incredibly awkward way and the pattern directions are a major fail at that point. I finished the 2nd dress a half hour before the party (Project Runway Make it Work Moment!) and didn't have a chance to take a picture, but it also turned out really cute. I added some narrow elastic into the side seams of the skirt to give it some poof.
