Does anyone know how much J Brand jeans are likely to shrink when washed? I would wash them in cold water and air dry.

After much searching, I just bought the J Brand '814' cigarette leg jeans. There is much to love about them, but I may do better with a larger size (which I cannot find in a store but could order from Nordstrom). I tried taking pictures of them, but they came out much too dark to see anything at all useful. The jeans are a very dark navy, which I love.

Thanks!
