I've been a jean wearer my whole life...I must say I have stayed away from pants because I haven't found one that fits "just right"...I'm a size 37/38 but I kind of have a prominent butt, not excessive but enough to cause an issue where the pants fit great in the seat but too loose in the waist and vice versa.
I want to make my first foray into buying proper pants and am looking for the staples. If I had to purchase 4 pairs of pants which do you all recommend? Color and style. Thanks!
What makes you think jeans are any more flattering than any other type of pant? And don't forget that you can get these things altered - if they fit great elsewhere but are loose in the waist, then take them to a tailor and have the waist taken in.
It's really impossible to answer your question in isolation, without knowing about what sort of clothes you want to wear these pants with, what you want to wear them for, etc. Really, you need to spend some time lurking and reading through the archive here to start forming your own opinion, then maybe come back with more specific questions. And this has doubtless been discussed before anyway, perhaps you could search for those discussions.
