DIANA dress form size c provides an adjustable body for accurate fitting, marking, and pattern work in home sewing or studio settings. It covers Dress Sizes 18–22 and uses dial adjustments with a stand that allows height changes, while the foam-backed nylon cover supports pinning. Use it to fit plus-size garments, adjust darts, and confirm seam placement, and re-check key settings as you sew so fit changes stay controlled and repeatable.
