I can’t believe these were only $13. They feel and look like quality jeans, very basic/simple boot cut. My daughter says they’re stretchy and comfortable. I ordered her a size 14 (12’s fit her waist but are always too short) She’s 11 years old, 5’ tall, about 80lbs. The waist adjusters were great for the perfect fit.

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!

These pants are good for $12.78 you can’t beat that only thing is the legs are a bit too long. Good quality jeans beats name Brand jeans that’s why I gave 4 stars not five stars she will grow in to them.
