Lucky Brand to American Eagle jeans size

The short answer

Lucky Brand 0 is American Eagle 2 by the two brands' own charts. 5 of 6 Lucky Brand sizes land on a different label at American Eagle.

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

On 1 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.

Every Lucky Brand size read across to American Eagle. US numeric sizes on the left, US numeric on the right.
