Women's Slim City Stretch Blazer vs Women's Linen-Blend Schoolboy Blazer: which is safer?

Where these two actually differ

• We flag DWR treatment chemistry (PFAS or fluorine-free unknown), Formaldehyde-based finishing resins, Elastane/polyester microfiber shedding and Coating degradation and water-repellent loss on the Banana Republic and not on the J.Crew.
• We flag Azo dyes and synthetic colorants and Formaldehyde from storage or finishing treatments on the J.Crew and not on the Banana Republic.
• The Banana Republic is Cotton blend with stretch finish, likely DWR-treated where the J.Crew is linen-blend, likely cotton-linen mix, unfinished, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the J.Crew is the one to buy.
• We are less certain about the Banana Republic grade, at 45% confidence against 78%, because it discloses less.
