I'm trying to decide between a 31 and a 32 NS.
The legs on the 31 are painted on (denim leggings), and I can't get the top button fastened. The legs on the 32 are slim but not tight, and I can get all of the buttons fastened with a bit of effort.
I like the fit of the 32, but I'm worried they're going to stretch too much. For reference, I measured my waist/hips where my jeans sit, and its 35.5".
