Don’t buy
Size: 2, Color: Navy
These are awful. Wide elastic on the back waistband. Sizing is way off. They’re at least two sizes too big.

Great pants, big pockets, order the right size
Size: 14, Color: Tan
I love these. Amazon thought I was a size 14 but I have to return those. I got a size 12 and love them. Very comfortable, and high waist. The pockets are huge which makes it seem a little weird if you don’t get a small enough size. I have wide hips and a big bottom, and instead of a size 14, a size 12 fits but will probably buy again and get a size 10 in the future. Great for work.

BEST EVER - But you may need to go up a size
Size: 14, Color: Blue Format
Absolutely the BEST jeans ever, particularly for over-50 women who like high-waisted jeans that don't look like "mom jeans." I cannot praise them highly enough. I've purchased four pairs!! The price is outstanding, the quality is superb, and they have ACTUAL pockets. (Why do manufacturers think women don't need real pockets?) I needed to order a size larger than the size guide indicated. The first size I ordered was both tight and too short. The next size up fit like they were made for me. The waistband has a stretchy, comfortable band sewn in that keeps it in place. No high-rise becoming mid-rise because they ride down. (For some of us, our waist is NOT the narrowest part of our torso so the waistband needs to be specifically designed to stay put.) The dark blue color will bleed, so wash by themselves the first time. These jeans look amazing - like those that cost WAY more! I promise you will NOT be disappointed. I wonder if I need a fifth pair...

Love these!
Size: 16, Color: Deepest Dark
I recently bought the Lee Women’s Ultra Lux Comfort with Flex Motion Skinny Leg Jean with Ever Fit, and I’m honestly so impressed. The first thing I noticed was how soft and stretchy the fabric feels without seeming thin or cheap. These jeans move with you all day, whether you’re running errands, sitting at work, or going out for dinner. The Flex Motion waistband is incredibly comfortable and doesn’t dig in at all, which is a huge plus for long wear.
The fit is flattering and true to size. They hug in all the right places while still being easy to move around in. I especially love that the Ever Fit design helps them keep their shape throughout the day, so they don’t sag or get baggy at the knees like some other skinny jeans I’ve tried.
The quality feels excellent for the price, and they look polished enough to dress up with boots or keep casual with sneakers. After washing, they held their color and shape beautifully.
Overall, these have quickly become my go-to jeans. Comfortable, flattering, and durable, they’re everything I was hoping for. I would absolutely recommend them to anyone looking for stylish everyday skinny jeans that truly last and feel amazing daily.
