I have thought about that, too, the Croquet Dress with long sleeves. I think the sleeves should look nautical. I have thought that the Jump Rope Dress long sleeve with the turned up cuff might look good or maybe the Book Report dress sleeve. I don’t think puffy sleeves would look good. I also thought about a bell sleeve but I think a straight sleeve would look better. I have changed sleeves around this week and what you have to do is make sure the arm hole and the top of the sleeve go together. You could use the top of the Croquet Dress sleeve and the draw the rest of the sleeve to be like the new sleeve. I did that yesterday with the Jump Rope Dress sleeve. I changed it into the Book Report sleeve. I wanted to use the cuff, the length, and the width of the Book Report sleeve. Will you post pictures of your modification if you do it?
