Depends on the particular pair of pants. For some order matters because of the particular placement of buttons. (Most are fasten-then-zip.)

What she said. I have two pairs of denim capris, which have both an outside and inside button. So, for those, I fasten the inside button, zip, then fasten the outside button. It's still fasten-zip, but there's an extra "fasten" involved :-)

I think the answer is predictable for men. Of course, I'm viewing this from the outside. :-)

I distinctly remember my mother telling me fasten then zip was the RIGHT way, even.
