Lululemon to 2XU leggings size

The short answer

lululemon 14 is 2XU XL by the two brands' own charts.

Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.

Every lululemon size read across to 2XU Flex & Fluid Tights. US numeric sizes on the left, Letter on the right.
