Lululemon to Athleta leggings size

The short answer

lululemon 10 is Athleta M or L 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 Athleta. US numeric sizes on the left, Letter on the right.
