Windsor maxi dress size missing but fits a medium

A very beautiful, long, casual or dressy maxi dress. Stretchy lace type material allows some stretch. It comes with a braided belt, but can be worn without. The beige attached slip underneath is about knee length possibly a little longer, and the sheer lace continues to the floor. Im about 5’6-5’7 and it goes to my ankles. Much prettier in person.
