Amazing jeans! My daughter loves them!
Size: 7 Slim, Color: Washed Blue, Size: 7 Slim, Color: Washed Blue
My daughter is really slim but tall. She is 7 about 50 pounds. She loves them and I’m so happy because all the other jeans that I buy I have to return cuz they are all too big on her. The jeans are stretchy and feel much more expensive for the price! Great quality! I will be ordering more for sure!

FANTASTIC FIT
Size: 16 Plus, Color: Washed Blue
I'm a 4'7" , 65 year old woman. Due to abdominal issues I needed jeans that give that extra something on the waist. I've tried on just about every brand of jeans ranging in size from adult/junior 6 to 12. If they fit on the legs the waist was huge. If they fit on the waist the legs and butt had enough room for me and a friend. I was resigned to wearing yoga pants and leggings with big shirts. My son mentioned that he loved the Amazon basics men's dress slacks, so I figured why not. First I looked at women's and juniors, and I knew from the measurements that I was still stuck. Then I remembered that about 15 years ago I'd buy girls pants (I was a size 12 in kids at the time) Looking at the sizes I knew a 12 was way too small, then I saw the 16 plus. With hesitation I bought them. Well glory be miss Agnes, THEY FIT. Comfortable, real jeans again. Sure, I have to take them up about 6 inches, but that's fine, not a problem. I'm just so happy to have real jeans again !!!
