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.

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.

MOM-1, PANTS-1...well, I guess we both win
Size: 32, Color: Black
Purchased for my 17 yr old son, about 6'2, 180, medium built. PROS -Black pair is a nice happy medium between faded black and pitch dark. -Roomy around the waist, but not enough for children to sag (no, no, no,) -excellent price for quality of product CONS -might be too comfortable for wearer, resulting in an request for an abnormal amount of additional pairs -consistent compliments for wearer could cause inflated ego or confidence OVERALL I didn't hear any complaints from my son or "can you return this" which is a WIN for me, bc he's usually very picky. it's a whole thing with the length and the thickness, color, all of it. I thought these pants looked really nice, the color was casual enough for friends, and dressy enough for church. I was pleasantly surprised. Not a big fan of belts, but he is not comfortable with sagging (thank goodness), and the fit around the waist provided enough support to stay where they needed to. Pants also did not scrunch up at the bottom, and did not fit like capris. Product title described product to a T (or pants): slim fit stretch comfort casual classic solid- it was all of those in one!
