>> 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

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.

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.
