The width from armpit to armpit is about 40 cm, and the length from the bottom of the round neckline in the front to the hem is about 64 cm. It's a beautiful dress that looks great with jeans! It's light, loose, and beautiful, and above all, it's comfortable to wear. It's 100% polyester, so it dries quickly. It also has a petticoat inside for peace of mind. It's new and unused, but it has been stored at home, so please refrain from purchasing if you are meticulous. Please understand that there may be some slight errors due to amateur measurements.
