This is a knitting pattern book. The pattern makes only one size, however that size will fit the following: Girl's 18/XL (35-37" waist), 20/XXL (38-40" waist); Junior's L (38-40" hips), XL (41-43" hips); Women's M (38-40" hips), L (41-43" hips); and Heights of 5' to 5' 5." The instructions are detailed (no graph), easy to follow, and in large print. This gorgeous dress whips up in no time because it requires the use of #9 knitting needles (not included) and light weight worsted yarn (also not included).
