I like Calvin Klein jeans and own several pairs in various shades of blue.  This was my first pair of black CK jeans.

Another reviewer noted that these need to be laundered before wearing, so I followed those instructions.  I noticed, however, that the jeans still had a fairly strong smell to them after washing -- evident even to me when I was wearing them, with my nose obviously a few feet away from the jeans.  I washed them a second time and they still smelled of some chemical smell.  The first time I wore the jeans, I wore black underwear.  The second time, I had on light colored underwear.  I was quite disappointed to see at the end of the day that the jeans had transferred a large spot of black dye to the underwear, making it look like I was incontinent.  I've since laundered those undies a few times using a few different types of stain removers and they still have a slight discoloration.

I'm still rating these 3 stars because I do think I'll like these jeans once I can wash and/or air the smell out of them, but I'll have to remember to only wear other black clothes when I wear these just in case the color continues to rub off on other garments.

In summary, I like the look of the dark black die but I wish the manufacturer had finished the fabric dye process with enough rinsing to remove the odor and tendency for the dye to transfer to other fabrics.
