This steel boned waist trainer is from luxx curves and is a size small. You can check their website for sizing details. This was purchased in 2018 so it does not have their logo added to the garmet and is by default a medium torso (11 inches) hardly warn, it’s too long for my torso. So it’s in great shape and again worn only a handful of times. Id say there’s basically no stretching on it as if it’s brand new. If you have any questions feel free to comment!
