    Not what is expected
    Size: Small, Color: Black-red, Size: Small, Color: Black-red
    There are buttons on the back that go all the way down that personally in my opinion ruins the style!! Will be returning because that is not what I expected.

    Faded Glory 😂 3.5 rating
    Size: XX-Large, Color: Black-red, Size: XX-Large, Color: Black-red
    Sooo faded I didn’t even want to try it on. And very dusty and ashy looking but only the red. It’s as if they had someone wear and wash it and return it and they took the red side and buttoned it onto another color and shipped it out. Guess these sellers like faded clothes. I wouldn’t buy certain colors seeing ppl talking about how the color doesn’t even last even upon its arrival. But if you have dye it’s your best bet to have some on hand when you order or even good for DIY projects. Good thing is I did try it on and it fits and feels like good quality with good weight to it. May have to go up a size I’m a female with big breast. Seems like it may last, just not the color. Good stitch work buttons seem sturdy. Yea these shirts would be great for DIY work

    Feel that flex without feeling that rubbery texture.
    Size: 36W x 30L, Color: Black
    These fit great! The texture isn't wuite like denim, more like a soft tablecloth, but that's quite alright. They have a flex that I need. Sometimes with "slim fit" stretch jeans, I feel a bit restrained in my thighs, this time, instead of ordering my usual size, I went up a notch. I can just wear a belt if I need to. I can fully articulate my legs in this set, in the stretchiness doesn't feel like weird rubbery velvet. They look good, they feel good. I imagine they'll last a bit longer than some of my other stretch jeans that had spandex or whatever in them.
