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.
