Because the shape of a skirt that is longer than one layer is very similar to that of a multi-layer big cake, one layer is bigger than the other, so everyone vividly named it a cake skirt!
The origin of cake skirts will be talked about in Victorian Elizabeth. At that time, the clothes they wore were conjoined cake skirts. At first, this kind of skirt highlighted the waist of women, so the skirt was very loose, but excessive fluffy would make people fat. So later, there was the present cake skirt, and the pleated design was inward as a whole, which would not cause the illusion of widening visually, but also changed in materials. Chiffon, mesh and other fabrics with good drape were used more.
