Here's a Free People dupe for ya!! The FP one is thicker material and the pants are shorter in length. It is very cozy and comfy so it makes sense that it sells out so fast all the time. The Amazon one is thinner but still nice material with longer pants. I usually hang my Amazon one to dry to help maintain the length due to being so tall and it has held up well. They both come in lots of colors! LTKsalealert LTKstyletip LTKunder50
