Hello Zanunai,usually,our tailors will adjust the costume size according to the measurement that you provide,it will be about 1-5 cm bigger,but it`s unable to estimate on different costumes.
If you need the costume in a specific size,you can choose 'costume size'(after choosing custom size),or you can write it in remark box (in order form), and our tailor will adjust it for you. n_n
