Hello Hannah Nespral, yes, the pants are included, since this is our commission series, so we can make it as your requested design. It is no extra cost for custom size, but our tailor will take 1 extra week to make the custom size (compare to the standard size costume).
Please submit ticket (with product link & request) to our
Support Center and let my teammate helps you directly. n_n
*If you order it, we will send you the actual product photos before ship it to you, and our tailor will adjust it if you don't satisfy with it, so please don't worry about this.
