I have worn 505's for years.  I bought these online because the information provided said 2% Spandex, which I like much better than Elastane because of the fit.  The pair I received had 1% Elastane [!] I tried them on and they seemed loose but I thought since I'd worn 8s before I thought they would shrink.  Washed them in HOT water and dried HOT.  They are still baggy.  My mistake.  So, because 8 Reg was not available here and I'd already washed them, I bought a pair of Sz 6 Reg elsewhere.  Perfect fit.  Actually, I love these jeans but still I do not like the Elastane.

I also bought same style 505 Black Ink with Checkmate, 8 Medium and while they are larger, especially in the stomach area, they are not as big so I kept them.  I have athletic legs and I don't think I could wear a Sz 6 in this jean.  The fabric is a lighter weight black cotton/poly w/1% Elastane.

I am 66 years old, athletic and trim.  I do not have a belly.  It is disturbing to me that Levi's have gone to adding room in the belly area and to using Elastane.  Why did they abandon the Spandex which helps with a baggy fit???
