Hello Nezumi, the dress length is proportion to the costume size.  It will reach around knees when you stand up (cover the knees), if you'd like to change the dress length, we can also change the length for you, please write it in remark box (in order form), and our tailor will adjust it for you.  n_n

Hello Natalie, the actual costume is just same as the photo shown; if you'd like to change the design, please submit ticket (with product link & request) to our Support Center and let our tailor check if they can make for you.  n_n
