If people like their jeans tight and fitted they should take their original size, it runs small by half size, so it won't real matter to them. If you like it bit roomy so size up. I sized up to 33 and the waist was really loose, and looked really funny. I took it to the tailor, I ended up giving it to my brother since the yellowish pair was too yellow to handle, after that I got another blind pair, and guess what, yellow again!! Had to resell it.
I think I'll look for braddom(for better cut, and I all the pairs I've seen here are blue) probably when amazon will cut it price again(damn! For a week in July it costed 156$, and a 20% coupon lowered it to 125$!!!)
All versions that I've seen in my diesel store had a yellow tint. I saw the blue version, only on Ebay. I would not pay big bucks for a yellow version.
