I made a unique dress. Left and right sleeve fabrics are different. Lace is used on the left sleeve, and both sleeves are also switched under the sleeves. The design points are diagonal buttonholes, two large triangles on the front (plain black), and the collar is cut and gathered. I added a two-stage flare to the back, and it felt cute and cool. The hem (2way) part can be put in a separate fabric, and a string can be passed through the switching part to adjust and change the shape.
