Hands down, my vote is for the larger jean because I think it is a more updated look. I'd second Angie's suggestion to play around with some of your tops before making the final decision.
But do take my opinion with a grain of salt because I'm in the process of purging most of my body-con items. I think I've just grown weary of the skinny, jeans-that-look-like-leggings and shrunken, short jackets that have held sway for so long. To my eye, a slightly looser fit is a more interesting shape to work with these days.
