Awkward sizing but decent fit
Size: 16, Color: Double Talk
I normally wear a girls 14 but had to size up with these. The waist was slightly too small while the length was right. After sizing up to a 16, the waist fit perfectly but the pants were too long. They look alright with heels or platform sandals but with any other type of shoe, they would need to be cuffed or shortened at the hem. I’m 4’11” and about 114lbs

Great quality
Size: 8, Color: Double Talk
Great quality jeans! My daughter needed blue jeans for her choir performance and I only found out right before the show. I’m so glad I could find a pair on Amazon and get it the next day — what a life saver! They fit well and she was so happy to wear her first Levi’s!

Nice fabric, comfortable, easy maintenance
Special Size: 27.5" Full Length, Size: Large, Color: Taupe, Special Size: 27.5" Full Length, Size: Large, Color: Taupe
I ordered a medium and they’re actually a size large. And they are just too large. I should’ve gotten the small, as recommended I thought I was ordering medium and I think I would’ve been OK with a medium, but where I usually wear a small and they sent me a large. It was just ridiculously large. They are lightweight and they are warm. I’m a senior and I’m thin so I get cold very easily especially in early morning and evening, so I like to wear them in the morning for my walks/yoga , they also work nicely under a longish skirt so it’s not so sheer… will definitely get more but will go with the small size. Just for reference, I’m 5 foot seven I usually wear a small or a size 5/6 usa size so these were too large, particularly in the waist just overall they were too large, but I think even if I got a small size they’re still gonna be kind of large in the stomach. I have an hourglass shape just for reference, but they are very comfortable, and I love the fabric. I am keeping them because I like the fabric and I really need them. I just will not wear them out of the house right now because they’re not fitting properly but next go round we’ll get the right size. Price was right they were having a sale so it was a bit of an impulse buy. But hello it was only 10 bucks! so that’s why it’s not worth sending it back for me. Overall, very nice quality and would recommend. Cats like the fabric too! 😸
