I found a couple of old blog posts, but I'm still not sure about boyfriend jeans. At first, I thought that they were a looser fit jean. Lately, I'm seeing loose and skinny alike, but rolled (various lengths from the knee down.) What makes jeans boyfriend jeans?

I bought a pair of Seven crops last week. The tag says boyfriend skinnys. I had them shortened (I love Nordstrom's alteration department. I was in Phoenix for a training and leaving the next day. They had them altered within an hour for me while I finished shopping.) Anyway, I'm not quite sure what makes them "boyfriend jeans."
