Whenever someone says that, I ask them would they buy a second-hand car? Or antique furniture? Or borrow a library book? Or use a public toilet?Fact is, the second you’ve worn something once, you are wearing used clothing every single day of your life. For the vast majority of stuff, it’s nothing that a good wash won’t fix. The rest, you leave in the shop. I’ve been wearing op shop clothing for years now, and am yet to catch anything communicable.
