Size: Medium, Color: Dark Cappuccino
The dark cappuccino brown is pretty. This is a favorite just because of the color of the tote. The inside lining color makes it easy to find items. I like it so much I ordered the black one.

Insanely great jeans for the price!
Special Size: Wide Leg Crop, Size: 12, Color: Medium Blue Vintage
I’m obsessed with these jeans. They’re comfortable and I think they legitimately look great. I had a baby 6 months ago and my body is “in transition” so I didn’t want to buy anything too expensive. These are cute, fit well, good quality. Excellent for short girls - I’m 5’ tall and they’re exactly the right length for a full-length jean. I feel like they’re fashionable without being too trendy (they work for 30somethings as well as 20somethings). They’re nice thick cotton with very little stretch. Because of that I’d be conservative with sizing because they do stretch significantly when you wear them. I got these in the lighter blue, too. The darker wash is slightly smaller and I wound up liking the color better, too. But the light wash is nice.

Surprising good - great quality for price.
Special Size: Wide Leg, Size: 6, Color: Ecru
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

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.

Cropped ones are better, size issue with full length pants
Special Size: Wide Leg, Size: 18, Color: Authentic Medium Wash
These are very small in the waist and about 8 inches too long (and I'm not even that short). Very well constructed though so I'll keep them on hand as I'm on a weight loss journey. These were an 18 and fit more like a larger 14. The cropped ones are AWESOME. I ordered a second pair in a different color. They fit absolutely perfectly and hit me around the ankle length wise. Adore them.
