Crew came under fire on Tuesday following reports that the specialty retailer is now offering items in size 000—the equivalent of an XXXS.

Blogs, including the well-known website Racked and the less high-profile Capitol Hill Style, called out the new size—which compares to a size zero in the U.K. or Australia—as a signal that vanity sizing has gotten out of control.

"I won't support J.Crew's decision to expand their sizing downward because it feeds into the notion that clothing size is a scarlet letter," Capitol Hill Style wrote. "The practical and reasonable thing to do would be to create a measurement's guide that isn't abhorrently dishonest, accepting that the brand now sells size 24 clothing."

A spokeswoman for J.Crew said the 000 tag has nothing to do with vanity sizing, a practice used by some retailers where they manipulate sizes to make shoppers feel like they wear a smaller number.
