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.

Favorite jeans ever!
Oh my gosh these jeans are incredible! People are always amazed when I tell them they are from Amazon. The quality is great. The stretch and feel is perfect and they are so flattering. I will be purchasing more. True to size!

My new go to jeans!!!
5'6", 235lbs, my jeans from LB were mostly size 18 - these 18 fit just as nicely if not better. They are a little long but since I wear boots every day working in the construction field, they do not drag. Love the extra high waist. Don't feel like I bare all when bending over. Needed to replace my jeans from a high dollar plus sized company that keep wearing thin in the thigh but hate the $60-$80 price per pair... again... I work in construction. First I just bought one pair. LOVED THEM the first time I wore them. After their first wash, they were just as great. No color bleed and no shrinking. I immediately ordered two more pair. This is the first pair of jeans I have fallen in love with for years due to their comfort. Appear to be of good quality. I think I look amazing in them which is not something I use often to describe myself. Don't appear to stretch too much during wear. I usually don't review products, but I know how frustrating finding a good pair of jeans can be, especially for larger ladies. I am so excited about and happy with these jeans, I just had to share.
