This material is thin but I wore a half-slip and a half-tee (white) underneath and that took dare of any shadows. I also wore the "89th&Madison Open Front Cardigan with Long Sleeves (black)"  and it looked sharp.  Wore for a whole day at an assembly (Bible discourses with theater type seating) and was never uncomfortable, and it never wrinkled up.  It is a tad shorter than I like so I placed a scarf across my lap.  I've bought Chicwe tops also and I've not had any problems with fit.  Always check their charts.
