Great, comfortable jeans.
Special Size: Low Stretch, Size: 34W x 30L, Color: Dark Midnight Wash
Great jeans! They're relaxed, but not loose or super baggy, so they still look great. I got the dark wash and you can wear them as dressy jeans or just casual out and about. I have bigger thighs and the 34x30 fits perfectly with room still to spare and not constricting at all. Whether it's walking around a lot, or sitting down for hours, it's very comfortable. We'll see how long they last but I washed them once already and are holding up. The length is good as well. When I don't have shoes I probably need a belt or could've ordered 29 length, but they're fine when I have shoes on. They don't slip down at all. Especially for the price compared to Levi's or others that cost 40, 50, or even $60 this is a great deal.

If you’re on the fence read this
Special Size: Low Stretch, Size: 40W x 30L, Color: Iced Light Wash, Special Size: Low Stretch, Size: 40W x 30L, Color: Iced Light Wash
In all honesty, I was skeptical about ordering jeans from Amazon. I’ve always bought my jeans in stores, but I figured I’d give it a shot. I ordered these jeans for an upcoming outdoor wedding because I wanted something lighter and thinner. They showed up today, and I threw them on. They fit great, feel good and comfortable, and they don’t look cheap. I’ll mainly be using these for outings, so I can’t really attest to the durability as far as working in them, but I’d still suggest them. For reference, I’m 5’8” and 230 lbs with a husky build—kind of fit, kind of fat.
