Hello Lorenzo, thanks for joining the cosplay~~
For the costume size, we provided both standard size & custom size, both are same price.
If you choose the standard size costume, please check if your body size (height, shoulder width, chest, waist & hip) are fit the size measurements in our standard size chart.
If you'd like to order custom size, please simply select the 'custom size'and fill up your exact body size, and our tailor will adjust the costume size to fit you. n_n
*Custom size costume doesn't charge extra cost, but the processing time will be longer than standard size costumes; for this costume in custom size, we need about extra 1-2 weeks to make it (excluding the shipping time).
