Size Guide How To Measure

Finding the right size is important for the best fit.

Important Size Notice 

Our costumes are based on Asian sizing, which generally runs smaller than US/EU/UK sizes.

Please DO NOT select your size based on your usual size. Always refer to the garment measurements provided on each product page.

If you are between sizes, we recommend choosing the larger size for comfort and easier alteration.

If you are unsure about sizing, feel free to contact us before ordering with your height, weight, chest (bust), waist, and shoulder measurements.

Size Chart

All measurements are garment measurements (not body measurements).

Please compare the measurements with your own clothing for the best fit.

All measurements are in cm and inches.

Unit conversion: 1 cm = 0.39 inch | 1 inch = 2.54 cm

All measurements are manually taken from the actual garment. A tolerance of 1–3 cm ( 0.39-1.18 in ) may occur. Different manufacturers may use different cutting standards. Please always refer to the size chart listed on the individual product page before ordering. For items with elastic waistbands: The elastic waistband provides a flexible fit and allows additional stretch for comfort. For the best comfort, your body waist measurement should be smaller than the listed maximum stretch measurement. Color may vary slightly due to lighting and monitor settings.

How to Measure

We recommend having someone assist you when taking measurements for better accuracy.

Shoulder: 
Measure straight across the back from one shoulder joint to the other. This is not measured in circumference.

Chest (Bust): 
Measure around the fullest part of your chest/bust. For female customers: Please wear a bra when taking this measurement. 

Waist: 
Measure around the smallest part of your natural waistline, which is where your trousers normally sit. Keep one finger between the measuring tape and your body for comfort.

Hip: 
Measure around the fullest part of your hips, keeping the tape parallel to the floor. For most of our straight-cut or loose-style pants, hip measurement is generally not restrictive.
