Here are a few designs I drew and have not created yet. The corset on the right has construction details on it because this is how the pattern will need to be made. It should not be made of knit and it will need to be underlined and lined to keep it’s shape. The green top has a seam down the back for the zipper to be placed there. The burgundy dress on the far left has no pattern details except elastic shown at the wrists and a piecing for color change at the bottom. That means this top must be made of knit because there are no darts or shaping seams on the top anywhere. Of course, choosing the right knit is imperative to make the garment look like it is illustrated. I would call this a sweater knit top because it shows some bulk. If it was made of a very fine synthetic knit there would be more folds in the sketch.In my booklet on my Etsy.com/shop/JohannaFashionWorld, site I have published : Knit Skirt No Pattern. It includes a basic understanding of knits to use for this type of garment. as well as a step by step walk through of building it. It is a good booklet for a beginning sewing project. I cannot emphasize enough “to be a fashion designer you must be able to build your first garment” Some day you will work with professional patternmakers and seamstresses who will be testing you to see if you know what you are doing in this competitive world of fashion. You will not always be sewing your own designs unless you want to be a professional tailor or seamstress.
