Size 0 and 00 were invented due to the changing of clothing sizes over time. Modern size 0 clothing, depending on brand and style, fits measurements of 30-22-32 to 33-25-36. Size 00 can be anywhere from 0.2 to 2 inches small than size 0.
The size zero is a term we use for extremely thin individuals, or trends associated with them.
But size zero was not always here. As mentioned, the numbers were invented due to the changing of clothing sizes over time. Some refer to it as vanity sizing or size inflation.
