To Select your pattern size, use your BODY MEASUREMENTS, not your Ready-To-Wear size.
All Simplicity patterns are Multi-Sized to help you get a Custom Fit.
Finished Garment Measurements are printed on the pattern tissue and on the back of many pattern envelopes. Compare these against the Body Measurement Chart for your size. The difference is the amount of ease allowed.
To Take Accurate Body Measurements: Follow the How To Measure steps on the How to Measure web page. Periodically check your measurements for changes.
Find your figure type: Use height and back waist length measurements and descriptions in Measurement Charts to determine your figure type.
