A measurment used on women's pants, shorts, skirts, and jeans. Traditionally a size 0 is a 23 inch waist, but sometimes it may be a 22 or 24. This size is considered ideal in
the world of
high fashion modeling, and most women don't
naturally have this so they often go to extreme lengths to achieve this.There is one size smaller, the 00, but many clothing companies don't carry this size, just size 0.
