LOL - well I don't know if mine are mom jeans or not but they fit me the way I like so that's what I buy.
I only wear Lee jeans - either Lee Riders or Lee Signature, boot cut. I'm pretty short (around 5' 3") but my legs are almost 30 inches long
So I have a very short waist and that makes it hard to find jeans that don't have a waistband that comes right up under my boobs!
The Lee jeans actually make me look like I have an area between my boobs and hips so that's what I buy, faithfully, for years. AND they are under $25 at Kmart
