I'm o.k. shopping at thrift stores, though I dislike that odd chemical/perfume odor from whatever they treat the clothing with. Usually they have a lot of air circulation, and I'm only there for an hour max. However, when I get home I need to keep the clothes bagged up tightly in plastic and in the basement until I'm ready to wash them. I react to the chemical/perfume a lot more in my closed up house, so I'm very careful with it.
