*This is really important - upper body patterns should be sized by the bust measurement.   Lower body patterns should be sized by the hip measurement.

Commercial patterns like Simplicity, McCalls, Butterick, Vogue, Kwik Sew, Burda, New Look, are easier to use, all of the information is printed on them for size alterations including back waist length, and they have seam allowances.

If you choose an independent pattern, be prepared to make more than one muslin.  Many independent patterns do not have the apex or the waistline marked, and some have no seam allowances  If you use a CAD program to make your pattern, your body measurements need to be accurate.
