OK, so this is a two-year-old thread that has got resurrected (has anyone noticed that this keeps happening lately?), but I'm going to chime in anyway!
Petites Anonymous, 'slouchy skinnies' and 'slim boyfriends' are the same thing, as I understand it. And if I were a taller woman, maybe I would wear my husband's jeans. (As it is, I'm almost the same size as you, so you're right, his jeans wouldn't come close to fitting). But that's the idea with 'boyfriend' jeans: they're supposed to look too big, like they could conceivably have been nicked from your boyfriend's closet.
I like boyfriend jeans. I like baggy butt pants. It's just another silhouette option for jeans. I like tighter-fitting jeans too. It's all good.
