Many thanks for all the replies - I'll be following up these shortly.
FYI, prior to posting, I'd found the following:

Unless intending to be Cleopatra (search for 'cleopatra images'), the dress style seems to be fairly simple but it's in the jewellery that makes the difference. Hair would seem to be straight and cut level, then there are the eyes.
Location
This is a bit more problematic. It's a bit too much for my flat to be turned into a temple or Tutankhamun's tomb, though the idea of creating a background is interesting and a few props for closer-up work may go a long way.
As for exteriors or large spaces, let's put an all expenses paid trip to Luxor at one end of the scale, closely followed by hiring Harrods (search for 'harrods egyptian interior images') but there have been fads for all things Egyptian in the UK - see

To be practical, and as a most likely one-off shoot, I'll be working on the 'less is more' principle.
