Cute, seem well made, good fit though run large (size down)
Size: 0, Color: Caramel
Super cute. Orange/rust isn't really my color but they were on sale so I thought I'd try. Washed and dried beautifully. I already wore them once and had no problems, they were comfortable with enough stretch but not so much that they were falling off. I like that they can be worn long or cuffed. I liked the length for my inseam which is about 28".
I did have to size down. Normally I wear a 2, but I ordered a 0 because it was less expensive lol. They fit perfectly. Definitely not too tight for my pear shape.
My weight ranges from about 112-116. My waist is around 25" and hips about 36.5", the largest part of my thighs measure about 21" around so I feel like they are good for those of us who are bigger/curvier on the bottom than the top. I'll likely order another in navy too!

Excellent value
Size: 12, Color: Eggshell White
I do like the fabric and lighter weight compared to similar style pants. They do run on the loose side, so keep that in mind. Excellent value

Great quality pants but does run big
Size: 0, Color: Tan
I was quite impressed with the fabric. It is a strong and sturdy cotton. The pants fit very well and I really like the partial elastic on the back. The elastic makes it fit well and a belt is not needed. I did size down based on the other reviews and I am so glad I did, it fits very well. I just put in an order for the navy blue ones.

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.
