When buying used jeans always make sure you can see the knee in the photo.I always try to include the knees and describe any flaws if they exist. Some people will fold jeans or pants so you do not see wear .If you are not sure ask for more pictures or a better description from the seller.It will save you money in the end. I would not bid on used jeans unless I could see them well or have a good description.
