If you bought the jeans a few years ago there is a chance the jeans have stretched with you. If you havent gained weight since then I would buy the 32s again. You could call the 1-800 number if you want to talk to the people who handle that brand. They might know something about the history of the fit or what other customers report...too tight or loose.
Buy the size you currently have and that fit. All men's clothing has a tolerance for ego. Your 32 tag is a 34 in reality. It's just the way it is ;)
:). Yes, that's what I'm saying
