I have, for most of my adult life. I try to buy the best I can access and wear things until they fall apart. Have said it before here, but until lockdown I had almost no experience of buying ‘loungewear’. My home clothes were simply my oldest and most ragged things.
I’m not in the least utilitarian though. I like lovely things, and see nothing wrong in evolving fashion - the art and craft and expertise that goes into producing the best, and the ability of really talented designers to interpret the zeitgeist and show us things we didn’t know we wanted. I’m just not interested in the throwaway mode of dressing.
(The same with food or household stuff: buy the best, use it, no waste.)
