How to find your size

Use the menu above to select the relevant gender, product type and brand. The tables provide sizing information with the product size displayed on one axis and the body measurements in inches and centimetres on the other. Find the measurements in the table which best match your body measurements to identify the most suitable size.



How to measure your body for clothing sizes


1. CHEST

Hold one end of the tape measure at the fullest part of your chest or bust, using the other hand to guide it under your arms and along your back until it meets. Ensure the tape measure is flat the full way around and horizontal to the floor for an accurate measurement.


2. WAIST

Place the tape measure on the narrowest part of your waist, wrapping it around until it meets. Refrain from holding the tape measure too tight as this will result in an inaccurate measurement.


3. HIPS

Standing straight with your feet close together, locate the widest part of your hips and bottom. Place one end of the tape measure at the widest point, guiding the tape the full way around until it meets. Ensure the tape is parallel to the floor.


4. INSIDE LEG

Take your shoes off and stand with your feet flat on the ground. Place the tape measure at the top of the inner thigh and measure the distance to the ankle.
