On Pinterest I have seen a lot of ruffly t-shirt dresses for dolls. When I realized that each time I saw one I repinned it to my “Sewing Ideas” board, I decided I’d better make one! I used this t-shirt pattern, with the 3/4 sleeve variation. I made no alterations to the pattern.
For the skirt part, I cut rectangles about 2″x20″ and 2 1/2″x20″. I gathered them separately, then attached with a finishing stitch to the top. I didn’t hem the edges on the skirt. All other seams are finished, besides the one that attaches the sleeves to the body.
If I were to do it again (which I probably will do in a different fabric), I would remove the hem allowance from the t-shirt before attaching the skirt. On this dress, the skirt begins a bit lower than I would like.
