Body Measurements and Fit Notes

Measure bust around the fullest part.

Measure hips around the fullest part.

Keep the tape level and not too tight.

Use inches or centimeters consistently.

Compare all three measurements, not just one.

If between sizes, check garment cut and fabric stretch.

Fitted dresses may need more precise measurements than loose styles.

Use neutral fit preference, comfort, and retailer charts to decide.

Brand Sizing and Vanity Sizing

Sizing differs by brand, retailer, country, and garment type.

Vanity sizing

The same body measurements may correspond to different labels across brands.

Fit and fabric

Stretch fabrics, relaxed cuts, and fitted styles can change size choice.

Special ranges

Petite, tall, maternity, and plus-size lines may use different proportions.
