Polyester clothing used to get ridiculed and now the average person is ensconced in it. The plastic leeches into your skin. The effect is even worse when you’re sweating or wearing the synthetic materials in the sauna. Then the effect is magnified when you wear “sustainable” clothing that’s made from recycled materials, because they’re made from already partially decomposed plastics leeching *even* more phthalates into your skin. Obliterate your polyester underwear, immediately.
