Body measurements and finished garment measurements answer different questions. The body chart identifies the pattern’s sizing basis; the finished measurements include its intended ease and design shape.
Measure the control points for the garment, then compare the pattern’s chart and schematic for the exact view. A blouse, fitted skirt and stretch top do not use the same fit checks. Confirm that the fabric meets the pattern’s stretch or drape requirements.
If your measurements cross sizes, follow the designer’s blending or adjustment guidance. Do not automatically size up whenever a finished measurement looks small: negative ease can be intentional in stretch garments, while inadequate positive ease can make a woven garment unwearable.
Make a toile or test garment when fit is uncertain. Check seam allowances and cutting instructions before cutting the final fabric. The commercial-pattern buying guide helps identify missing information before purchase.
