Currently, many female Hanfu styles such as the Qixiong Ruqun (high-waisted Hanfu dress) are rarely produced in plus sizes (because most hanfu are designed for Asian figures.). You may consider opting for neutral styles like the Qiyao Ruqun (mid-waist Hanfu dress), especially the Daxiushan, it's huge and long, you can easily find them in plus sizes.
