Cotton is one of the most pesticide-y crops (chemical insecticide used on cotton crops account for 25% of global consumption--ick), which is why you should try to avoid all the foods (mostly snack foods and bad salad dressing) that use cottonseed oil. This oil is cheap because it's extracted as a byproduct from cotton, which is technically not a food, so they can spray it will all the really bad non-food-grade pesticides. When people jibe me for spending so much of my limited writer's income of organic products, I like to retort, "Well, think of how much $ I'll save in chemotherapy." It really is a matter of You get what you pay for. Health--of selves, and respecting and conserving the earth--is priceless!
Pictured are organic, non-toxic-dyed cotton undies from Cottonfield USA.

I like them because the covered elastic seams are extra-comfy, nice line esp. for low-rider jeans, kudos to Yeumei Shon for designing such a great looking and wearing product. I can already tell from one washing these will last a loooong time, which actually makes them a smarter buy than the 99-cent undies I used to buy that fell apart in a few washes. There are many other styles to choose from, and don't forget the MAN FERTILITY.
