Fully lined and the length was decent. I'm 5'9" with a short torso and long legs. I think it might not work for someone with a longer torso. The lining kept me warm without feeling hot and it stretched so I didn't feel constricted. It also prevented the sequins from poking into my skin. The sequins can catch on to each other. This happened a few times so it's definitely something to consider. Overall, I was happy with the outfit.

I’m 5’6 and curvy and I usually need XLarge clothes but I purchased an Large jumpsuit and it fits perfectly
