Two or three years ago I regularly bought size 34 CK at Costco and they fit fine. But now when I got size 34 from Amazon they were way too big. Maybe measuring scales are changing as everyone gets fatter? I heard them calling it "manity" sizing on the news.

So I returned the 34s and ordered the 32 size which seem a good fit. I have a slim ass and am definitely not a member of the big genitals club. This current version seems more silky light stretchy material compared with the cottony thicker material of the ones I got a couple years ago. But maybe I had a different style? This style is U1000. It seems to have a somewhat lower rise in front than the previous ones I had, which would be sexier if I was sexy. It'll take some wash cycles before I can judge if these are really significantly better than the five pair for $10 Hanes I can get at the local Walmart.

Added later: After washing a few times the CK underwear (about $8.50 per unit) just don't seem that much better than Hanes I get at WalMart (about $2.50 per unit). In fact the Hanes seem to have kept their softness better. So I'm definitely not going to pay three times as much for CK.
