From Lara Sanner:
Shirt, shirtdress or dress: your choice! This pattern includes all the pieces you need to build a wardrobe of comfortable and combinable garments. The back has three different versions thanks to the versatility of the yoke. The 3 versions of the yoke is what allows you to have up to 9 different versions of one pattern. You can choose between the sleeve version, which you can wear in two positions, or the version without sleeve, with a narrower shoulder.
Learn new techniques or improve your sewing level with the detailed instructions which will guide you through the garment´s construction: collars, plackets, bias binding or pockets are some of the techniques included in the sewing guide.
