I think there should be some special uniform, probably just very minimal underwear and a short shirt/ tunic, worn by women condemned to be crucified. It would be distinctive, with clear markings proclaiming our condemned status. Our undies would be tanga or thong style briefs and a basic back-tie bra, and we'd strip off the top before being scourged, and for the parade of death, so we'd be near enough bare for beating. If we're raped before being crucified, we'd need to be naked, but I think being minimally covered while dancing on the cross might be more erotic than completely nude - at least until my Executioners decide to rip the last scraps away.
