SOOOOO firs of all these jeans look just like the picture when you get them, so let's start there! I have lost weight so now i weigh 252lbs, small/medium belly, 5'8 height with thighs and booty. I would way if you weight too much more than that and your belly is bigger, get the 18plus. these jeans do have nice stretch to them which i love. They really hug/fit my curves nicely and they do make the booty look really good too! The material is soft and i can move easily in these. I love the little detail of freyed material down the sides of the jeans, that adds a cute little touch to them. Again i love the color and it's true to color and true to sizing. Definitely super happy with these jeans and i can not wait to wear them!
