I purchased the Cute Christmas Girls dress and blouse pattern 152/153/154 without carefully checking the US size equivalent. Now that I have printed the pattern I see that the smallest size is a 110/5(US). My grandaughter that I am sewing for is usually a size 3 (US) pattern. Looking at the Burda size chart she would better fit the size 92/2. Her chest size is 20", Waist 21" and Hips 22". This is my first pattern sewing with BurdaStyle and I also noted that you have to add 5/8’ seam allowance to cutting out material. How can I easily convert this pattern to her size or should I just forget it. I really wanted to make the blouse and sleeveless dress right away! I don’t have her available all the time to size and fit. Please advise!
