Nothing wrong with these fits, they don't flatter your backside much but I don't think that can be helped, you're a really skinny guy. To be honest both of these look decent and the stacking is great, I remember more than once people mentioning how great those 19cm's fit you (as an example of a good dior fit) so it's quite odd to see so many people call you out on them now. I wouldn't worry about it, if you were to post this in Sufu or walk around melbourne like that very few would be negative about the jeans and a good few would even compliment you on them.
Older gen slimfit first worn around July '06, daily wear through July '07, and then worn on occasion after that. One soak, one machine wash. Throwing them in the machine, by the way, was the best medicine for these jeans. In short, please buy RRL.
Some progress pics on my New Standards, about 5.5 months since I got 'em, over the past 2 they've been alternated pretty evenly with Ande Whall Cougars. So I guess ~4.5 months of wear. Thoughts? I'm thinking about a wash soon.
