Hello Eleonora galiotto, maybe you can make a custom size so that it can fit you much more perfect, please simply select the 'custom size' and fill up your exact body size, and our tailor will make your costume size as required. 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).
