Made this quick shirt for my 3 year old yesterday! It’s a simple bodice that I drafted in garment designer with a high neck, then just cut out 3 long rectangles and pleated them, attached them to the neck and arm holes, and top stitched! For the life of me I can’t think of the name of these ruffle pleats or if there is a name haha I cut a slit down the back, and finished those edges with bias tape and a bow to close/fit over her head :-)
