The SP has her clothes on so it must be OK.
When I see a SP I have showered at home within the hour and all clothes I wear are recently washed.
I have no idea what other SPs are wearing but for incall I receive in pretty skimpy stuff and sometimes will have even lost the top by the time you’re out of the shower (depending on the experience requested of course)
Even for outcall, I change into skimpy stuff or at least sexier stuff when I arrive.
if you come out with your clothes on I will ask you to shower again and come back with clothes off mainly because otherwise the flow of the appointment will be fucked up because now I have to figure out how to get all that off you.
