Well, I’m still using 45 year old strap goods I got as a teen.
But from my Rerider Phase I just realized that my collection of discount store cotton polo shirts are mostly at the ten year mark. And the Ralph Lauren and Tommy Hilfiger ones especially are neither faded, pilled, or noticeably shrunk. They get worn in full sunshine 6 months of the year. I’ve never had that lifespan from general fashion or work tops.
My 5 year old Cavallo breeches are however fading on the thigh and starting to get that puckered thinning thing spandex does. But they have been in much more frequent rotation than the tops (4 breeches, 15+ tops).
