Lucilla's "Rich Matron" and Deleted Execution Dress
This dress appears briefly and mostly in shadow in the movie, but it also matches up with the dress from the cut execution scene which is reintegrated in the extended version. It's a gold sheer crinkled silk with a printed flower pattern. I believe it works something like a sari and is just wrapped around her. There would need to be a pin or other fastening to hold the top corner in place at her back. A wrap is pinned to the shoulder and attached to a bracelet at the wrist. It is covered by a green cloak when she visits Maximus; the same cloak as with her green dress. The wrap is moved to cross her chest and she has a dark striped stole with her. Also note that in the close-ups during the reintegrated execution scene she's wearing the wrong earrings.
