Although I read all the reviews, some questioning the authenticity of the product, I was desperate to finally find a pair of 505's.  Just like many said, the sizing wasn't very accurate and they ran large and long for a 14 Medium and even though they were not the style that were "stretch" they stretched out and lost their shape so fast in a short wearing that I had to rewash them right away.  They also faded very badly in the wash, both before I wore them and after the second washing which was I'd never had a pair of Levi's do before. Sadly, they look nice at first but I'd be hesitant to purchase another pair online.
