Banana Republic black summer silk dress with twisted straps size 8P

Approximate measurements in photos. Some pleating in front and back. Zips up on the side. Drop waist with twisted straps and pleating. Silk material. Cool and lightweight. Summer or dress up. There is a little piece of material on each twisted strap in front and it appears to possibly be sewn closed (may have been designed that way not sure). You cannot see it from the front.
