Preventing bodice lining from rolling into view at arm and neck holes

I'm making a jumper of medium-weight corduroy, and I found a nice fat quarter of what looks like a Liberty lawn that I'd like to use to line the bodice. This is the Music Box Jumper, by the way. The bodice lining is cut the same as the bodice outer fabric. I am wondering if this combination of fabric weights will cause the lining fabric to roll out at the arm and neck holes. If so, that would be glaringly obvious, because the corduroy is dark blue and the lining is a light, multi-colored print. I know I can edge stitch the lining at the lower neck to secure it there, as the pattern instructs, but there is no opportunity to do so at the other edges because of the way the bodice is constructed. As I see it, my options are: *Edge-stitch the arm and neck holes on the outside of the garment. (But I don't think I'd like the resulting flatness there.) *Use piping around the armholes and neckholes. (Unnecessarily fussy for this project.) *Choose another lining fabric (I actually have one that is the same color as the outside fabric, so any roll would not be obvious.) *Trim and clip to a fare-thee-well to reduce the bulk of the corduroy seam allowances so they will not assert themselves by pulling the lining fabric out. Advice solicited! Thank you.
