I have a 40 inch bust measurement. I have, however, 49.5 inch hips (I've lost half an inch. Go me.) I am given to understand that this is slightly out of proportion with the rest of the world. However, most women are not perfectly shaped. A bust measurement on a sweater is not enough. Giving a width at the hips or at the bottom of the sweater would be lovely. I can probably figure out how much I'm going to have to adjust your pattern without it, but it sure would help. Hrmph.
love,
me
