When I call something jeans, I usually think of blue jeans. These have a similar heavy fabric like jeans but they are not made of denim. I went to Talbots recently because I needed some black pants and all of their pants were thick and I complained that if I was in the office, I would be sweating in these thick lined pants. (Where I live, it rarely gets below 60 degrees.) The woman showed me summer clearance pants and that is what I considered cotton type work pants. I am pretty sure that the length is 42 inches because that is what I usually wear but I will check later after we get home and include it in the description. I think the only way I can take a pic of them laying out is if I stood back a distance and I take these on my break at work so I am not sure where I can do that. (which is why all of the pics except the baby clothes, show my clothes folded.)
