Essentials Girls' Uniform Classic Fit Short-sleeve Shirt Xl[12] vs Boys Classic Fit Flat Front Pant: which is safer?

Where these two actually differ

• We flag Azo dyes and heavy metals in colorants on the Amazon and not on the Dickies.
• We flag Azo dyes and colorants, Heavy metals in dyes and pigments and Residual solvents or sizing agents on the Dickies and not on the Amazon.
• Both carry a flag for Antimony in polyester, so neither choice avoids it.
• The Amazon is cotton blend, standard school uniform shirt where the Dickies is cotton/polyester blend, no special coatings, 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.
