^I don't really have much more info than that lol.
It really depends on how tight you want them and your comfort level. Don't expect to be able to move around easily if you size down. They'll stretch, but it's not a fun process.
^agreed on the contrived bit. If they were actually your boyfriend's jeans and you were wearing them then ok, I can dig that. But, buying oversized, "boyfriend" labelled jeans is just dumb imo. And the ones I've seen look awful.
