My neighbour, who is maybe 45-50 with a nice average weight type figure (curvy from waist to hip in her case), was wearing mom jeans yesterday. I think they do emphasize the curve from waist to hip but I don't feel that's necessarily a bad thing. Because she's not a hipster and the jeans were clearly unintentional, they do look dated, but not "unflattering" per se. No more so than skinnies on those of us with bigger hips and thighs, something the eye definitely had to adjust to after boot cuts.
