I sized UP, as when I tried them on I thought they fit good with the stretching, but I'm afraid as I'm wearing them they will STRETCH too much so they will not fit as good. This is true right? The issue is...If I size down then I can hardly button them up and such....I purchased a 33, but I'm usually a 31..... in waist, cause I wanted the fit I was looking for.... Please help! It depends on what kind of fit you want. Just wear them and see, since jeans won't reveal their true fit until they break in, and I doubt you could return them as new now. Besides, it's a learning curve for everyone. If you haven't soaked or washed them, keep in mind that washing and machine drying may still shrink them more, so you have that as a backup. And if they stretch out too much, you'll know better next time.
