Love them!
Size: 7 Slim, Color: Washed Blue
I did but expect these jeans to fit so well and look so nice on my daughter. Hands down the best jeans I’ve purchased for her, much better fit and quality than the other stores! The length is perfect, but it’s a little snug in the waist. Still a great fit with some stretchiness! Great value!

Great pair of Jean and great price!
Size: 14, Color: Washed Blue, Size: 14, Color: Washed Blue
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.
