I have not read this whole thread, just first page, but just had to add my pick of Mom Jeans.
I found them at Kohls, they are Lee Comfort Waistband jeans. Yes, they are stretch but they are so comfortable. I have always worn jeans but since getting older with middle age spread they have not been comfortable. The ones with elastic seem baggy and no hip pockets.
When I found these Lees, my grand daughter commented "Granny, where did you get those sexy jeans?" Made this fat granny feel pretty good!!!
