Why Sub-Zero Sizes Exist
Vanity sizing's downward drift. Before the 1980s, the smallest size was 2 or 4. As brands sized down their patterns to flatter customers, the original 4 became the new 8. To accommodate genuinely small bodies that no longer fit the new "size 4," brands added 2, then 0, then 00, then 000. See vanity sizing explained.
