The article about Eric Rheinhart in The New Yorker says the following:

In an effort to optimize the dressing process, he alternates between two pairs of jeans, and orders nylon or polyester T-shirts from Amazon, wearing them for a few weeks before donating them. When the clothes get smelly, he puts them in the freezer, to get rid of the odor. “Sometimes, during the day, a couple of hours will do it,” he told me. “I’ll wear a towel.”

I tried that over the summer, where I would wear the same black polyester T-shirt as an undershirt every day, then I would hang it up overnight to air it out. It took on the odor of my underarm deodorant, and the freezer trick sort of works. But eventually I would have to launder the T-shirt anyway after a couple weeks and then hang it up to dry.

Because of current economic trends, I suspect our standards of personal hygiene in the U.S. will see regression towards the mean in the coming years, where we'll learn to tolerate body odor again and wear clothing cleaned less often to match.
