    Color is awesome but material isn’t.
    Size: 34W x 32L, Color: Blue, Size: 34W x 32L, Color: Blue
    The color is pretty much as advertised. I wear a 33 so I order up a size and they were both too long and too big. Instead of returning them I washed them and put them in the dryer. The length after washing turned out perfect but the waist is still a little too big. It should also be noted that the quality of the material isn’t the best. After washing them this is how the pockets will look. You have to iron them each time to get them flat again. I would buy again because of the variety of colors but only at a cheaper price.

    Runs small
    Size: 36, Color: Khaki
    The jeans are a nice color, and length… they run SMALL… I wear a 33-34 and bought a 36. They were skin tight but breathable material… I sent them back to order a 38

    I’m happy with the jeans
    Size: 40, Color: Pink
    I am very satisfied with this purchase. A lot of compliments too. They fit well, stretch to the material but the skinny fit look. The quality so far is great.
