If a couch is still looking good and dates from the 60s, it's going to keep looking good if you care for it.

I've never had a couch half as good as the MCM ones I've scored on Marketplace.

I had a pair of wool-topped fleece lined Harris Tweed duck boots from LLBean when I lived in New York, lasting eightish years in my hands. Built like a brick shithouse, incredibly cozy and durable, I sold them when I moved to the PNW and actually turned a profit because they were limited edition. They were still very functional and undamaged despite years of commuting through nasty city snow and slush and salt, as well as some work on a boat in dry dock. If you got black ones they would absolutely be classy enough to commute in (though demand a change to indoor shoes in an office).

Pricier, but worth it especially if you want something with a lovely and durable real fleece lining.

Jumping in here as someone who grew up on a specialist sheep wool farm, I would highly recommend commissioning a knitter to make you a sweater in a style you like, to your measurements, from Wensleydale wool--its a rare UK breed and has wonderful, slightly shiny, durable long staple fibre. Soft enough to wear against my sensitive skin. Not cheap, but definitely (esp if you hand wash carefully and flat dry, and learn to darn) a BIFL option.

I'd avoid your typical Aran shop--the tourist and international trade means, as said above, that they don't often use legit local wool and it's often lower quality and itchy.
