Vanity sizing

Gradual increase in size of ready-to-wear clothing of the same nominal size

Vanity sizing, or size inflation, is the phenomenon of ready-to-wear clothing of the same nominal size becoming bigger in physical size over time. This has been documented primarily in the United States and the United Kingdom. The use of US standard clothing sizes by manufacturers as the official guidelines for clothing sizes was abandoned in 1983. In the United States, although clothing size standards exist, most companies do not use them any longer.
