Comes with silk undergarments as shown in first 2 pictures. I wore with a matching slip skirt instead. Happy to include both when renting so you can decide how you want to wear it. Set and skirt are both size large. I am a size 10. Think this could comfortably fit size 8-12. Was a bit loose on me. Rental cost includes price to get dry cleaned. If you want to get dry cleaned yourself then you can lower rental price. Thanks!
