Choose your size using body measurements. These are manufacturer guide measurements, rather than the finished dimensions of an individual garment.
- Measure your chest or bust, waist and inside leg.
- Compare those measurements with the relevant chart below.
- Choose a size offered on the product, and check its fit and leg-length information.
Numeric waist sizes: where the product specifies a waist size in inches, choose that waist measurement. A waist size and an EU clothing label are different numbers.
