Anne-Marie Bubble Romper sewing pattern (0/3mths to 5T). The Anne-Marie Bubble Romper is slightly loose-fitting for comfort and movability, and she has some excellent features. She has a curved front, a gathered bubble bloomer bottom, two ruffle options, and a snap placket crotch for easy diaper changes. The designer rates her project as easy to make and therefore suitable for a beginner sewist. SewModernKids
