From pattern description: Instead of the usual shawl, why not wear a fun and fuzzy ballet sweater over that sleeveless or short-sleeved dress? The three-quarter-length sleeves give it a dressier feel, and the dramatic ties make the fit more flexible. This pattern fits a small to medium woman (30- to 34-inch chest). Directions to fit medium to large (36-40) and large to extra large (42-44) are in parentheses. These is a certain amount of give in the sizing, due to the overlap of the right and left fronts of the sweater.
