Hello Sharanika Akter, we put a pannier under the costume when taking product photos, but the pannier is not included. 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 my teammate helps you directly.  n_n
