Wearing pants too tight is not the only reason to prefer a little give though. Men's styles are loose and relaxed on male born bodies, which is not necessarily the same ratios we need. Many people have told me that my pants look too big on me, in a sloppy goofy way, and not in a manly way. But the hip and butt is still tight to be comfortable moving around, and then they end up looking tight in the butt and loose in the waist and calf. My hips are pretty damn wide for the rest of my body and a little bit of stretch means that I can wear pants that are a little closer to fitting without obviously or uncomfortably being tight in the hip. When I'm just standing around, they look loose and when I work or move around a lot, they give a little bit in the hip and thigh so they don't look like they're too small. Most of my pants don't have it, but the ones that do, I like.
