The button is super wobbly and feels like itll break at any moment. The zipper quality also isnt great even when im not wearing them the zipper cant go above like 80% when I wear them itll slowly unzip if I twist or turn my body over a few hours. There's also not a lot of room for your bits so maybe go a size up. Other than that rhe material is comfy and has a bit of give so unlike other skinny jeans you dont feel restricted. The color is also super vibrant and lovely. Im not gonna return them unless the zipper breaks but idk if ill buy another pair if the button is like this.
