Where these two actually differ

  • We flag Azo dyes and synthetic dyes and Allergic contact dermatitis from dyes or finishes on the Aisle and not on the Dear Kate.
  • We flag Synthetic dye allergens and heavy metals, Elastic degradation and microplastic shedding and Undisclosed allergens in synthetic materials on the Dear Kate and not on the Aisle.
  • The Aisle is Organic cotton, wood pulp fiber where the Dear Kate is Organic cotton with synthetic elastic, which is most of the difference in these two grades.
  • The gap is 30 points, wide enough that this is not a close call, and the Aisle is the one to buy.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
