I AM Irma, a dress and I can also be made as a shirt. I have a concealed button placket, my front is shorter than my back and on the back I have a back yoke with a large box pleat. I have a shirt collar and you can choose between classic shirt sleeves or bishop sleeves maintained by a cuff. All seam allowances are included in the pattern. The pattern is enclosed in an envelope. It contains the sewing pattern along with a step by step illustrated explanation guide. The different pieces overlap with each other so you will need to trace the pattern on paper.
