Women's Linen-Blend Schoolboy Blazer vs Women's Unlined Cotton-Blend Blazer: which is safer?

Where these two actually differ

• We flag Azo dyes and synthetic colorants and Formaldehyde from storage or finishing treatments on the J.Crew and not on the J.Crew.
• We flag Azo dyes and colorant safety, Antimony in polyester component and Microplastic shedding from synthetic fibers on the J.Crew and not on the J.Crew.
• The J.Crew is linen-blend, likely cotton-linen mix, unfinished where the J.Crew is Cotton-blend, unlined blazer, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
