Reformation to NYDJ jeans size

The short answer

Reformation 29 is NYDJ 6 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 Reformation size read across to NYDJ. Waist size sizes on the left, US numeric on the right.

Tinted rows change label or sit between two sizes. 5 sizes have no counterpart on the NYDJ chart. Read from the two charts only; no formula and no averaging.

What wearers say
