Hello Brian, cosplay costumes will fit kids, teenagers & adults. The most important thing is to measure & check the chest size, waist size & hip size; if the standard size doesn't fit you, you can choose 'custom size' and fill up your body measurements, and let we tailor made the costume size for 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 3 weeks to make it (excluding the shipping time).
