Calvin Kleinwomens Plus Size Tulip Sleeved Seamed Sheath Dress

Does the dress fit above the knee or midi length? I like my dresses over the knee to midi length

Am normally a size 18, 200 pounds 5'2 but some reviews suggest to size down, should I?

Is the dress lined?

I’d like to know if this dress fits tight , if it runs true to size ? If a person has to order a size up for comfort fitting.I don’t like tight fit
