Hello Marina, don't worry, we can tailor made the costume size as customer ordered.
*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).
*Our costume sizes are more similar to Asian size, so the standard Medium size is smaller than US or European medium size.
