Love these jeans
Size: 12, Color: Iced Blue Light Wash
These a comfortable and flattering pair of jeans. They are length is too long for me but, they have a wide hem and taking them up one hems length makes them a perfect fit for me. This is an easy fix if they are too long. They are well made and a good value in today’s market.

Great jeans but order a full size down if like to fit snug
Size: 10, Color: Iced Blue Light Wash
love these jeans so far. I have a hard time buying jeans and have only really loved Maurice’s everflex. But now found these. Have only had them a few weeks but so far love them. I am normally a solid size 12. I ordered these in a 12 and thought they fit perfect at first. I even washed and dried them and they were fitting nice. But upon wearing them one time, they really stretched out by the end of the day. To the point I felt they were too big. I decided to order a 10. I don’t ever wear a size 10. But so far they are perfect. They were pretty snug to get on but stretch out to fitting perfect after wearing a bit. I like my jeans tight around my middle section. But the legs are still loose and fit great. Size down if you like them tight around your middle/no gapping. They are also the perfect length even when sizing down. Not too short or way too long. 5’6-7” and about 180 pounds.

Love the high waist and fabric!
I absolutely hate jean shopping, I also don't like spending$60+ on a pair of jeans. I have purchased Amazon Essentials items in the past and feel like the quality is good so decided to try these out. These are almost perfect. I do feel the sizing is off. I wear Size 13 in Wax Stretch Jeans and had to order a 16 for these. They are a bit long but i was able to fold them in once at the cuff. I would have given them 5 stars however the waistband is NOT stretchy. I do love the high waist fit however the waist does not stretch at all which is why i probably had to size up. But the overall stretch is good. I loved these so much I ordered the skinny jean version and those fit good as well, but same issue with the no-stretch waist band. I hope they keep the style and fabric of these because I fill definitely purchase again. It's a true black color. The fit is very flattering.

Almost had it.
For a $30 pair of jeans, the quality was pretty good. They fit nicely from the waist to mid thigh. Comfortable even on a plus size frame. From there it’s a trash fit. Basically a wide leg jean with minimal flare. May look good on someone taller but I may as well have been wearing an old pair of ufo pants. If you’re on the shorter side and looking for an old AE skinny kick look, these pants are not it.

Love these jeans! Flattering, comfy, tts fit, good price
Size: 16, Color: Iced Blue Light Wash
I love these jeans. I'm 5'7 and normally wear a 16 in jeans. These fit perfectly, it carry all my weight in my midsection and hips and the rise on these is high which I like, but there's enough room and stretch in the waist that they don't dig in. I ordered these when the price was around 23 dollars, which I think was an excellent value, I am going to order the other wash as well. They're not too thick but not too thin, perfectly stretchy but don't get stretched out, and they're comfortable. The leg opening is the perfect amount of flare without being like a bell bottom.
