Buying another color
Size: 18, Color: Rinse Wash
Love these jeans. Fit true to size. Ankle length and I just over 6 ft tall.

Comfortable jeans. Perfect length. Too baggy for my body shape.
Size: 0, Color: Medium Wash, Size: 0, Color: Medium Wash
5’0 - 95lbs I got size 0. They are comfortable, but really baggy. The length sits perfect at my ankles. The quality of the jeans are also nice. Pockets are a good size.

Too high waisted
Size: 14, Color: Black
I really wanted these jeans to fit because I loved the style and the heavier weight with just a touch of stretch. Size 14 should have fit but was huge. High waist is an understatement; the waist hit between my bellybutton and my boobs. The whole body area - waist, butt, crotch was huge. Sad because I liked the look of the legs...just the right amount of width and the length hitting the top of my Chelsea boots (26" exactly, I measured) plus the wide cuff. I'm not sure if going down a size or two will change how high the waist goes.

I’m smitten
Size: 18, Color: Black
These are so well made and perfect high-rise to keep my belly tucked away. Have the perfect stretch without making me sausage like. Keep shape all day! Great length and look so cute with all kinds of shoes. Can’t wait for sweater weather!

Disappointed
Size: 12, Color: Medium Wash
Jeans were a different style than what the photo shows. They are also a size 12 but run TINY couldnt even get them up my thighs and I’m a true size 10. Run like a size 7.
