I finally had a chance to sort this out this morning.
I liked the way my regular size fit - baggy and loose.
But I much preferred the way the size up fit - *very baggy and loose*. Dropped crotch galore. Love that. They come off really easily without undoing the button or fly. They barely stay on sans a belt, which is how I am wearing them today. The tight tapered hems give them structure somehow and they stay on! They kind of grab onto my calves for dear life. Weird but it works.
Yes. You will eventually see photos of the fit. Next outfit post. Promise.
Just thought this info might help others, so I posted my thoughts right away. Eventually there will be a visual.
