I have been buying Levi's 529 for years. In fact, within the past 6 months, I bought 3 pairs, all different dyes, etc. They fit great. So, when I saw this 2 button version with fancier pockets, I thought sure! They arrived. I can't even get them on. I'm wearing a pair of 529's right now in the same size. They fit great. I'm not sure why/how a different button and pocket could have an affect on the size. Unfortunately, it seems that it may be a question of workmanship.
