>> Would I buy clothes or furniture from Costco?

Careful - even Gen-Z is looking at Kirkland clothing for certain pieces, and some furniture (like the Murphy bed I bought from them) is better when it's bland and greige

No hate on people who buy that stuff - I like more eccentric style/colors and a specific fit that I've never seen at a Costco (athletic/form fitting vs bulky). Something like pajamas pants I would consider, but otherwise I've never had luck with their clothing and their furniture usually doesn't fit the decor of my house. I did snag a great kitchen island there last year that's held up really well, but otherwise I really don't like their couches, chairs, lawn decor, etc

I've found that the price of Costco dress shirts is good enough that I can just buy 4-6 at a time, pay to get them all tailored to be form-fitting, and I'm still hitting a good value:effort.

Costco also has a decent rotation of non-Kirkland "mall" brand clothing that frequently changes (probably intentionally so you have to come in regularly). My wife is always looking to find and replace the Lucky Brand t-shirts she found once in there.

I've heard good things about their wool socks.

They used to be better but I stopped buying them after COVID related supply chain problems lowered the quality, at least a few years ago. Dunno if they rebounded. Supposedly they are made in the same factory as Smartwool

That seems improbable. I have bought "merino" socks from Costco and they are only something like 20% merino. I also have Smartwool socks and they are quite different.

I actually like Costco's generic black-and-orange athletic sock as a daily driver. I treat them poorly; we take off our shoes in the house but not socks. As they wear out, I throw them away; once a year I buy a new pack to refresh the losses. I use the Smartwool for activities but otherwise take good care of them. They last.

Yeah I never bothered to verify the claim of them being made in the same factory and only heard it from word of mouth from some folks.

Making two products in the same factory does not necessarily mean they are identical.

I paid like $30 for Jeans from Costco 3 years ago and I'm shocked at how well its held up considering I wear it 90% of days.
