J. Crew recently introduced a new size, 000 or XXXS.

The extra-extra-extra-small size is for customers with a 23-inch waist. The company said the line was designed for smaller petite women, and was introduced in response to growing demand from customers in Asia. It’s available in Hong Kong and also online.

Just to give you an idea, a 23-inch waist is about 11 inches smaller than that of the average American woman, and is about the same circumference as a basketball.
