Cute jeans
Size: 12, Color: Washed Blue, Size: 12, Color: Washed Blue
Bought these jeans for my daughter and they fit great! The material is thick, which is nice even in warm weather. They look just like the photo and have a great length to them. Very comfortable and stretchy . She loves them!

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 !!!

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.
