Excellant value
Special Size: Wide Leg Crop, Size: 14, Color: Rinse, Special Size: Wide Leg Crop, Size: 14, Color: Rinse
Purchased the “cropped” length. I am 5ft 3.5 inch. Weight 170lbs (42 inch hip/38 inch waist) normally wear a size 10/12 or 31 in jeans, depending on the brand. I ordered up at 14 for these based on other reviewers. (When held up to other jeans they were the same as a Talbots 10 at the waist) Prewash they felt good, a little big& length hit at the top of my foot. After wash and dry, the fit was almost perfect and the length was at lower ankle. Ordering up is probably the right choice, although I think I could have been comfortable in a 12 (with no drying). They are a tad bit too long for a “cropped” look IMO. The wide leg is a true wide leg and falls straight from the waist. The material is heavy and there is almost no give/stretch - so a traditional denim. This is the dark blue and it is a true dark blue. You can’t beat the price, excellent value.

Be careful when washing!!!
Special Size: Wide Leg Crop, Size: 12, Color: Iced Blue Light Wash
Loved the jeans but after I washed them only after wearing one time, the color got completely stained. I washed on gentle with like colors and somehow the entire jeans turned splotchy. So upsetting because the fit and feel were great.

Great Jeans!!
Special Size: Wide Leg, Size: 8, Color: Stone Dark Wash
I love these wide leg jeans! The denim is thicker and more durable than I was expecting, especially for the price. These are a great quality! I get compliments on them every time I wear them and people are surprised when I tell them they're Amazon Basic brand. They fit true to size as I followed the size guide. From now on my jeans will be this brand!

Surprising good - great quality for price.
These are great for the price. They run a little wide in the waist so I sized down from an 8 to a 6 and they fit perfect. They are a true wide leg - so don’t buy if you are looking for something more straight leg or flair. The quality of the denim is very nice. I’m actually surprised and the quality. These do not feel stretchy which is good for the style. Very happy. Hopefully they hold up after washing

Very thick fabric
Special Size: Wide Leg Crop, Size: 8, Color: Black
Great quality. Would have been 5 stars, but the material is very thick and stiff. They do run small, but long. I ordered the 8, I’m 5 foot. They needed to be hemmed about 4 inches.
