Better jeans than I expected
Size: 29W x 34L, Color: Rinse, Size: 29W x 34L, Color: Rinse
I pretty much only wear Levi's 510s & as of lately Asos skinny jeans. Thought I'd give these a shot. I wear between 28w-30w so I ordered 29w. They fit good & seems to be really true to size. I could have probably ordered the 28w for a tighter fit. Only reason I didn't give them 5 stars is that the dye transfers from the denim. I'm sure eventually that will stop happening?? I like the dark denim so I don't wanna continue to wash them so they fade out so soon.

Depends on how it fits you I guess
Size: 33W x 29L, Color: Rinsed
They're okay, but don't really fit me well for some reason. Loose in the hips, tight in the crotch, they're supposedly my size based on other jeans. Back pocket of all stretch styles is too loose; wallet falls out too easily.
